This type of heat diffusion differs from mass diffusion in behavior, only in as much as it can occur in solids, whereas mass diffusion is mostly limited to fluids.2.In steady state conduction, the amount of heat entering a section is equal to amount of heatcoming out. In this conduction, all the laws of direct current electrical conduction can be applied to “heat currents”. In such cases, it is possible to take "thermal resistances as the analog to electrical resistances. Temperature plays the role of voltage and heat transferred is the analog of electrical current.3.Conduction is the transfer of heat by direct contact of particles of matter. The transfer of energy could be primarily by elastic impact as in fluids or by free electron diffusion as predominant in metals or phonon vibration as predominant in insulators. In other words, heat is transferred by conduction when adjacent atoms vibrate against one another, or as electrons move from atom to atom. Conduction is greater in solids, where atoms are in constant contact. In liquids (except liquid metals) and gases, the molecules are usually further apart, giving a lower chance of molecules colliding and passing on thermal energy.4、F ractional distillation is one of the unit operations of chemical engineering. Fractionating columns are widely used in the chemical process industries where large quantities of liquids have to be distilled. Such industries are the petroleum processing, petrochemical production, natunil gas processing, coal tar processing, brewing liquified air separation, and hydrocarbon solvents production and similar industries but it finds its widest application in petroleum refineries . In such refineries, the crude oil feedstock is a very complex multicomponent mixture that must be separated and yields of pure chemical compounds are not expected, only groups of compounds within a relatively small range of boiling points, also called fractions and that is the origin of the name fractional distillation or fractionation. It is often not worthwhile separating the components in these fractions any further based on product requirements and economics.5、H eat transfer is the transition of thermal energy from a hotter object to a cooler object (“object” in this sense designating a complex collection of particles which is capable of storing energy in many different ways). When an object or fluid is at a different temperature than its surroundings or another object, transfer of thennal energy, also known as heat transfer, or heat exchange, occurs in such a way that the body and the surroundings reach thennal equilibrium; this means that they are at the same temperature. Heat transfer always occurs from a higher- temperature object to a cooler-temperature one as described by the second law of thermodynamics. Where there is a temperature difference between objects in proximity, heat transfer between them can never be stopped; it can only be slowed.6、F ractionating columns help to separate the mixture by allowing the mixed vapors to cool, condense, and vaporize again in accordance with Raoult ' s law. With each condensationvaporization cycle, the vapors are enriched in a certain component. A larger surface area allows more cycles, improving separation. This is the rationale for a Vigreux fractionating column or a packedfractionating column. Spinning band distillation achieves the same outcome by using a rotating band within the column to force the rising vapors and descending condensate into close contact, achieving equilibrium more quickly.7、A fractionating column or fractionation column is an essential item used in the distillation of liquid mixtures so as to separate the mixture into its component parts, or fractions, based on the differences in their volatilities. Fractionating columns are used in small scale laboratory distillations as well as for large-scale industrial distillations.J8.The closed system design required for achieving and maintaining the low-pressure atmosphere inside the dryer also provides advantages for processing a hazardous material.Examples include toxic chemicals or solvents and explosive materials. The vacuum dryer safely contains and condenses the hazardous vapors from such substances without any threat to your workplace environment or outside atmosphere. With some hazardous materials, you can provide further protection by using inert gas to limit the oxygen level in the vacuum dryer.9.Crystallization is the (natural or artificial process of formation of solid crystals precipitating froma solution, melt or more rarely deposited directly from a gas. Crystallization is also a chemical solid-liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs.10.Radiation is the transfer of heat energy through empty space. All objects with a temperature above absolute zero radiate energy at a rate equal to their emissivity multiplied by the rate at which energy would radiate from them if they were a black body. No medium is necessary for radiation to occur, for it is transferred through electromagnetic waves; radiation works even in and through a perfect vaccum. The energy from the Sun travels through the vacuum of space before warming the earth.11.Precipitation reactions can be used for making pigments, removing salts from water in water treatment, and in classical qualitative inorganic analysis. Precipitation is also useful to isolate the products of a reaction during workup. Ideally, the product of the reaction is insoluble in the reaction solvent. Thus, it precipitates as it is formed, preferably forming pure crystals. An example of this would be the synthesis of porphyrins(口 |、l林)in refluxing propionic acid. By cooling the reaction mixture to room temperature, crystals of the porphyrin precipitate, and are collected by filtration.12.Here vacuum drying provides a unique advantage. By controlling atmospheric pressure, the vacuum dryer increases the effective A T for a given process. That is, vacuum drying simple reducesthe boiling point - or vaporization temperature - required for removing the liquid. By controlling pressure and the heat introduced to the dryer, you can significantly increase the effective △ T and thus dry the material faster than at normal atmosphere. For this reason, a vacuum dryer is especially suited to drying a heat-sensitive material that degrades above a given temperature and would otherwise require a lengthy drying cycle. Examples of such materials are vitamins, antibiotics, and many fine chemicals.13.Separation processes can essentially be termed as mass transfer processes. The classification can be based on the means of separation, mechanical or chemical. The choice of separation depends on the pros and cons of each. Mechanical separations are usually favored if possible due to the lower cost of the operations as compared to chemical separations. Systems that can not be separated by purely mechanical means (e.g. crude oil), chemical separation is the remaining solution. The mixture at hand could exist as a combination of any two or more states: solid-solid, solid-liquid, solid-gas, liquid-liquid, liquid-gas, gas-gas, solid-liquid-gas mixture, etc.14.An important stage of the precipitation process is the onset of nucleation. The creation of a hypothetical solid particle includes the formation of an interface, which requires some energy based on the relative surface energy of the solid and the solution. If this energy is not available, and no suitable nucleation surface is available, supersaturation occurs.15.In operation, the vessel rotates about the trunnions4 axis. The integrity of the seal around the stationary vacuum line - which extends through the trunnion and is angled upward into the drying chamber's top, above the material in the rotating vessel - is critical for maintaining the dryer's vacuum. During rotation, the material cascades inside the chamber, gently tumbling and folding to bring the material into contact with the heated walls. This action makes the dryer especially suitable for handling friable and fragile materials that can't withstand shear from agitation, such as polyethylene terephthalate (聚对苯二甲酸乙二醇酯)pellets. The delumping (粉E卒I的) bar can be operated intermittently to break up undesired agglomerates.16.Similar to surface tension, adsorption is a consequence of surface energy. In a bulk material, all the bonding requirements (be they ionic, covalent, or metallic) of the constituent atoms of the material are filled by other atoms in the material. However, atoms on the surface of the adsorbent are not wholly surrounded by other adsorbent atoms and therefore can attract adsorbates. The exact nature of the bonding depends on the details of the species involved, but the adsorption process is generally classified as physisorption (characteristic of weak van der Waals forces) or chemisorption (characteristic of covalent bonding).17.At low driving temperatures, no boiling occurs and the heat transfer rate is controlled by theusmil single-phase mechanisms. As the surface temperature is increased, local boiling occurs and vapour bubbles (气泡)nucleation, grow into the surrounding cooler fluid, and collapse. This is sub-cooled nucleation boiling and is a very efficient heat transfer mechanism. At high bubble generation rates the bubbles begin to interefere (扰动/干扰)and the heat flux no longer increases rapidly with surface temperature (this is the departure from nucleate boiling DNB). At higher temperatures still, a maximum in the heat flux is reached (the critical heat flux).18.As a liquid mixture in the round bottomed flask is boiled, vapor rises up the fractionating column. The vapor condenses on the glass platforms (known as tray (塔板)or plates) inside the column, and runs back down into the liquid below and refluxes the upflowing distillate vapor. The hottest tray (塔板)is at the bottom of the column and the coolest tray is at the top. At steady state conditions, the vapor and liquid on each tray is at equilibrium. Only the most volatile of the vapors stays in gas form all the way to the top. The vapor at the top of the column then flows through the water-cooled condenser, which cools the vapor down until it condenses into a liquid distillate (偕出液).The separation may be enhanced by the addition of more trays (to a practical limitation of heat, flow, etc.)19.Natural methods of precipitation include settling or sedimentation , where the solid forms over a period of time due to ambient forces like gravity or centrifugation. During chemical reactions, precipitation may also occur particularly if an insoluble substance is introduced into a solution and the density happens to be greater (otherwise the precipitate would float or form a suspension. With soluble substances, precipitation is accelerated once the solution becomes supersate rated. In solids, precipitation occurs if the concentration of one solid is above the solubility limit in the host solid, due to e.g. rapid quenching (淬火)or ion implantation, and the temperature is high enough that diffusion can lead to segregation (偏析)into precipitates. Precipitation in solids is routinely used to synthesize nanoclusters.20.Freeze-drying also causes less damage to the substance than other dehydration (脱水)methods using higher temperatures. Freeze-drying does not usually cause shrinkageor tougheningof the material being dried. In addition, flavors, smells and nutritional content generally remain unchanged, making the process popular for preserving food. However, water is not the only chemical capable of sublimation, and the loss of other volatile compounds such as acetic acid (vinegar) and alcohols (N宰)can yield undesirable results.。
绍兴文理学院2021级大一化学专业英语上学期期末考试试卷附答案
2021级大一英语上学期期末考试试卷附答案Part II Reading Comprehension (30 %)Directions: There are four passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.Passage OneScience is not a set of unquestionable results but a way of understanding the world around us. Its real work is slow. The scientific method , as many of us learned in school, is a gradual process that begins with a purpose or problem or question to be answered. It includes a list of materials, a procedure to follow, a set of observations to make and, finally, conclusions to reach. In medicine, when a new drug is proposed that might cure or control a disease, it is first tested on a large random group of people, and their reactions are then compared with those of another random group not given the drug. All reactions in both groups are carefully recorded and compared, and the drug is evaluated. All of this takes time and patience.It’s the result of course, that makes the best news—not the years of quiet work that characterize the bulk of scientific inquiry. After anexperiment is concluded or an observation is made, the result continues to be examined critically. When it is submitted for publication, it goes to a group of the scientist’s colleagues, who review the work. Einstein was right when he said: “No amount of experimentation can ever prove me right, a single experiment can at any time prove me wrong.”In August 1996, NASA announced the discovery in Antarctica of a meteorite(流星) from Mars that might contain evidence of ancient life on another world. As President Clinton said that day, the possibility that life existed on Mars billions of years ago was potentially one of the great discoveries of our time.After the excitement wore down and initial papers were published, other researchers began looking at samples from the same meteorite. Some concluded that the “evidence of life”was mostly contamination from Antarctic ice or that there was nothing organic at all in the rock.Was this a failure of science, as some news reports trumpeted?No! It was a good example of the scientific method working the way it is supposed to. Scientists spend years on research, announce their findings, and these findings are examined by other scientists. That’s how we learn. Like climbing a mountain, we struggle up three feet and fall back two. It’s a process filled with disappointments and reverses, but somehow we keep moving ahead.21. The author’s main purpose in writing this passage is to state that ____________.A) most scientific discoveries are not reliableB) mass media is misleading because it looks at the research results onlyC) scientific research is a process filled with reverses and requires slow and patientworkD) repeated experiments are necessary before medicine can be used in patients22. Publication of a scientific finding signifies __________.A) a challenge to fellow scientists to prove it wrongB) the end of a processC) the beginning of a new scientific inquiryD) the soundness of the result23. Einstein’s words are used to show that he thought___________.A) experiments have proved him rightB) scientists do not need so many experimentsC) one experiment is not enough to prove him wrong.D) scientific ideas are never free from challenge24. NASA’s announcement of the discovery of evidence of ancient life on Mars shows _________.A) the way human beings learn about natureB) the failure of the scientific methodC) the fruitlessness of human search for life on another worldD) the excitement brought by scientific findings25. It can be inferred from the passage that the media is interested in __________.A) the process of scientific researchB) the results of scientific researchC) the scientists who do the researchD) the effects of scientific research on human lifePassage TwoNormally a student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses each lasting for one semester. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and anotherduring his degree course, though this is not in fact done as a regular practice.For every course that he follows a student is given a grade, which is recorded, and the record is available for the student to show to prospective employers. All this imposes a constant pressure and strain of work, but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm. The effective work of maintaining discipline is usually performed by students who advise the academic authorities. Any student who is thought to have broken the rules, for example, by cheating has to appear before a student court. With the enormous numbers of students, the operation of the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.26. Normally a student would at least attend __________classes each week.A) 36B) 12C) 20D) 1527. According to the first paragraph an American student is allowed _______.A) to live in a different universityB) to take a particular course in a different universityC) to live at home and drive to classesD) to get two degrees from two different universities28. American university students are usually under pressure of work because_________.A) their academic performance will affect their future careersB) they are heavily involved in student affairsC) they have to observe university disciplineD) they want to run for positions of authority29.Some students are enthusiastic for positions in student organizations probably because_________.A) they hate the constant pressure and strain of their studyB) they will then be able to stay longer in the universityC) such positions help them get better jobsD) such positions are usually well paid30. The student organizations seem to be effective in _________.A) dealing with the academic affairs of the universityB) ensuring that the students observe university regulationsC) evaluating students’performance by bringing them before a courtD) keeping up the students’enthusiasm for social activitiesPassage ThreeDoreen Sykora is now a junior at Mcgill University. She had a difficult time when she first began college. She said, “I was always well prepared for my examinations. But I would go in to class to take the exam, and I would fall apart. I could not answer the questions correctly-----even though I knew the answers! I would just blank out because of nervousness and fear.”Hitoshi Sakamoto, an anthropology student at Temple University in Tokyo reports similar experiences.These two young students were experiencing something called test anxiety. Because a student worries and is stressed about a test, his or her mind does not work as well as it usually does. The student cannot write or think clearly because of the severe tension and nervousness.Now there are special university courses to help students. In these courses, advisors and psychologists try to help students by teaching them to manage test anxiety. Such a course helps students learn to live with stress and not fail because of it. First students take a practice test to measure their worry level. If the tests show that their stress level is high, the students can take a short course to manage the fear. These courses teach students how to relax their bodies. They get training to become calm in very tense situations. By controlling their nervousness, they can let their minds work more easily. Learned information then comes out without difficulty on a test.Doreen Sykora saw immediate results after taking such a course. She now has enthusiasm about the relaxation methods. “Mostly, what I do is imagine myself in a very calm place. Then I imagine myself picking up a pencil. I move slowly and carefully. I breathe easily and let all the tension out. With each breath, more worry leaves me. It really works too. My grades have improved greatly! I’m really doing well at McGill now. This relaxation method works not only on examinations, but it has improved the rest of my life as well.”For Hitoshi in Tokyo, the results were much the same. He is enjoying school a lot more and learning more.31. Doreen Sykora and Hitoshi Sakamoto were filled with nervousness and fear during examinations because they were__________.A) not ready and unaware of the answersB) physically so weak that they fell apartC) subject to test anxietyD) unable to write or think clearly32. The higher the students’worry level is, __________.A) the less calm and relaxing they areB) the more difficult they will be trained to manage fearC) the more stressed and tense they areD) the longer courses they will take to manage fear33. What’s the purpose of some special university student-help courses?A) To help students to reduce test anxiety.B) To show a stress level experienced by students.C) To learn more knowledge about test anxiety.D) To have a better understanding of test anxiety.34. What’s the meaning of “blank out”in paragraph one?A) To be like a blanket.B) To be sure of an answer.C) To be relaxed.D) To be unable to think clearly.35.Which of the following best sums up the organization of the passage?A) Examples----theories----ideas.B) Problem----strategy----examples----results.C) General statement----examples----result.D) Strategy----experiment----examples.Part III Vocabulary and Structure (15 %)Directions: There are 30 incomplete sentences in this part.

Then mark the corresponding letter on the Answer Sheet with a single line through the center.Language is a signaling system which operates with symbolic vocal sounds (语声), and which is used by a group of people for the purpose of communication.Let’s look at this 66______ in more detail, because it is language, more than anything else, 67_____ distinguishes man from the rest of the 68_____ world.Other animals, it is true, communicate with one another by 69_____ of cries: for example, many birds utter (发声) 70_____calls at the approach of danger; monkeys utter 71_____ cries, such as expressions of anger, fear and pleasure. 72_____ these various means of communication differ in important ways 73_____ human language. For instance, animals’cries do not 74_____ thought and feelings clearly. This means, basically, that they lack structure. They lack the kind of structure that 75_____ us to divide a human utterance (发声) into 76_____.We can change an utterance by 77_____ one word in it with 78_____: a good illustration of this is a soldier who can say, e.g., “tanks approaching from the north”, 79_____ who can change one word and say “aircraftapproaching from the north”or “tanks approaching from the west”; but a bird has a single alarm cry, 80_____ means “danger!”This is why the number of 81_____ that an animal can make is very limited: the great tit (山雀) is a case 82_____ point; it has about twenty different calls, 83_____ in human language the number of possible utterances is 84_____.

Naming Inorganic CompoundsIntroduction:1.10 million known chemical substances.Need to establish a set of rules leading to informative, systematic name for each substance.2.Nomenclature: basic rules for naming simple compounds (organic compounds,inorganic compounds)Contents of current section:1.Preparatory materials(names of common elements in the periodic table);2.Ionic compounds (cations, anions,compounds);3.Acids;4.Molecular compounds Common Elements:Ac-Actinium锕, Ag-Silver, Al-Aluminum, Ar-Argon, As-Arsenic, Au-Gold, B-Boron, Ba-Barium, Be-Beryllium, Bi-Bismuth, Br-Bromine, C-Carbon, Ca-Calcium, Cd-Cadmium, Ce-Cerium铈, Cl-Chlorine, Co-Cobalt, Cr-Chromium, Cs-Cesium铯, Cu-Copper, F-Fluorine, Fe-Iron,Ga-Gallium镓, Ge-Germanium锗, H-Hydrogen, He-Helium, Hg-Mercury, I-Iodine, In-Indium, Ir-Iridium铱, K-Potassium, Kr-Krypton, La-Lanthanum镧, Li-Lithium, Mg-Magnesium, Mn-Manganese, Mo-Molybdenum钼, N-Nitrogen, Na-Sodium, Nb-Niobium铌, Nd-Neodymium钕, Ne-Neon, Ni-Nickel, O-Oxygen, Os-Osmium锇, P-Phosphorus, Pb- Lead, Pd-Palladium钯, Po-Polonium钋,Pt-Platinum, Pu-Plutonium钚, Ra-Radium, Rb-Rubidium铷, Re-Rhenium铼, Rn-Radon氡, Ru-Ruthenium钌, S-Sulfur, Sb-Antimony锑, Sc-Scandium钪, Se-Selenium硒, Si-Silicon, Sm-Samarium钐, Sn-Tin,Sr-Strontium锶, Ta-Tantalum钽, Te-Tellurium, Ti-Titanium, Tl-Thallium, U-Uranium, V-Vanadium钒,W-Tungsten, Xe-Xenon, Y-Yttrium钇, Zn-Zinc, Zr-Zirconium锆Ionic compoundsGeneral rule :The names of ionic compounds are based on the names of the ions of which they are composed. The positive ion (cation) is always named first and listed first in writing the formula for the compound. The negative ion (anion) is named and written last.Eg.:NaCl (sodium chloride)Naming cationsMonatomic ions (take the name of the element itself)Zn2+ (zinc ion), Al3+ (aluminum ion)Note: for an element (especially transition metals) with more than 1 positive ion, the positive charge of the ion is indicated by a Roman numeral in parentheses following the name of the metal: Fe2+ --- iron (II) ion, Cu+ ---copper (I) ionIf unsure, use the Roman numeral designation of charges as part of the name.Naming cationsNote: A widely used older method to distinguish between two differently charged ions of a metal is to apply the ending –ous for the lower charged ions or -ic for the higher charged ions, respectively. They are added to the root of the Latin name of the element.Eg.:Fe2+ (ferrous ion), Cu+ (cuprous ion)Fe3+ (ferric ions), Cu2+ (cupric ion)Naming cationsPolyatomic cations: Groups of atoms with a positive charge.NH4+ --- ammonium ion Hg22+ ---mercury (I) ion or mercurous ionNote: Hg2+ ---mercury (II) ion, or mercuric ionCommon ions:Cations: ammonium, cesium, copper(I) or cuprous, hydrogen, lithium, potassium, silver,sodium.(+1 ions); barium, cadmium, calcium, cobalt(II) or cobaltous, copper(II) or cupric,iron(II) or ferrous, lead(II) or plumbous,magnesium, manganese(II) ormanganous,mercury(I) or mercurous, mercury(II) or mercuric, nickel, strontium, tin(II) or stannous, zinc.(2+ ions); aluminum, chromium(III) or chromic, iron(III) or ferric.(3+ ions) Naming anionsMonatomic anions (named by dropping the ending of the name of the element and adding the ending -ide ):Naming anionsPolyatomic anionsNote: only a few polyatomic anions end in -ide:OH- hydroxide ion, CN- cyanide ion O22- peroxide ion, N3- azide ionNaming anionsOxyanions (polyatomic and oxygen-containing):when an element forms two oxyanions, the name of the one containing more oxygen ends in-ate; the name of the one with less oxygen ends in -ite: Eg.:NO2- nitrite ion, SO32- sulfite ion ,NO3- nitrate ion, SO42- sulfate ionNaming anionsNote: when the series of anions of a given element extends to three or four members,prefixes are also employed. The prefix hypo-indicates less oxygen, and per- more oxygen:Eg: ClO- hypochlorite ion, ClO2- chlorite ion ClO3- chlorate ion, ClO4- perchlorate ion chlor---root of chlorineNaming anionsPractice: selenate ion (?); selenite ion (?) perbromate (?) , hypobromite (?)Note: exceptions to rules: permanganate ion is MnO4-, manganate ion is MnO42-. ferrate-(or perferrate) FeO4-,chromate CrO42-, dichromate Cr2O72-Naming anionsPolyatomic anions with hydrogen ionsThese ions are named by prefixing the word hydrogen or dihydrogen, as appropriate,to the name of the hydrogen-free anion.Alternative way is to use the prefix bi-:Eg.:HCO3- hydrogen carbonate (or bicarbonate ) ion; HSO4- hydrogen sulfate ( or bisulfate) ion; H2PO4- dihydrogen phosphate ionCommon ionsAnions: acetate, azide, bromide, chlorate,chloride, cyanide, dihydrogen phosphate,fluoride, hydride, hydrogen carbonate or bicarbonate, hydrogen sulfate or bisulfate, hydroxide, iodide, nitrate, nitrite, perchlorate, permanganate, thiocyanate, cyanate. (1- ions);carbonate, chromate, dichromate, ferrate,hydrogen phosphate, oxide, peroxide, sulfate,sulfide, sulfite, thiosulfate.(2- ions); nitride,phosphate, phosphide. (3- ions).Naming ionic compoundsWrite the formulas for ionic compounds by combining the names of cations and anions:barium bromide- BaBr2copper(II) nitrate or cupric nitrate- Cu(NO3)2aluminum oxide-Al2O3mercury(I) chloride or mercurous chlorideHg2Cl2ferric oxide, Fe2O3Practice : Name the following compounds:(a)K2SO4;(b) Ba(OH)2;(c) FeCl3 (d) NH4Cl;(e) Cr2O3;(f)Co(NO3)2Write the chemical formulas for the following compounds:(a)calcium carbonate; (b)sodium fluoride; (c) iron(II) perchlorate; (d)magnesium sulfate; (e) silver sulfide; (f) lead nitrate.Naming AcidsAn acid here is defined as a substance whose molecules yield hydrogen ions (H+) when dissolved in water.Rule : The name of an non-oxyacid is related to the name of the anion. Anions with the ending -ide associate with acids having hydro- prefix and an -ic ending:Eg:Chloride (Cl-) to hydrochloric acid (HCl) sulfide (S2- ) to hydrosulfuric acid (H2S)Note: only water solution of HCl is called hydrochloric acid, the pure compound is called hydrogen chloride.Naming the acidsFor acids derived from oxyanions (oxyacids)Rule: If the anion has an –ate (-ite) ending,the corresponding acid is given an –ic (-ous) ending. Prefixes are retained:Naming the acidsExercisesName the following acids:(a) HCN, HSCN; (b) HNO3, HNO2 (c) H2SO4 (d) H2SO3Give the chemical formulas for(a)hydrobromic acid; (b) phosphoric acid.Naming molecular compoundsRule:The procedures for naming binary (two-element) molecular compounds are similar to those for naming ionic compounds.

化学专业英语期末备考知识汇编(二)
一、Nomenclature of Inorganic Compounds(Ⅰ)(无机化合
物命名Ⅰ)
二元化合物(binary compounds):
1、无机化合物由两部分组成,显正价的部分为金属、氢或者其他带正电的基团,他们的命名放在前面;显负价的部分为非金属,他们的命名放在后面。
2、二元化合物:仅含有两种不同的元素,命名规则:阳离子元素符号+阴离子词干+词根ide:
(1)正电性元素有固定的氧化态的二元化合物,并且这两种元素只有一种化合物存在时,命名同二元化合物,即:阳离子元素符号+阴离子词干+词根ide
Eg: CaBr2 Calcium brom ide溴化钙
Mg3N2 magnesium nitr ide氮化镁
KI potassium iod ide碘化钾
(2)含变价金属的二元化合物:
当一个化合物中金属不止一种氧化数时,用写在括号中的罗马数字来标明氧化数。
命名规则:阳离子元素符号+(罗马数字)+阴离子词干+词根ide
Eg:FeCl2iron(Ⅱ) chlor ide氯化亚铁
FeCl3iron(Ⅲ) chlor ide氯化铁
CuCl copper(Ⅰ)chlor ide氯化亚铜
CuCl2 copper(Ⅱ)chlor ide 氯化铜
(注:当一种金属只有一种氧化态时,就不需用罗马数字标明价态)传统命名法中,若一种金属只有两个氧化态,用-ous标明低价态,用-ic标明高价态。
Eg:FeCl2ferr ous chloride 氯化亚铁
FeCl3ferr ic chloride 氯化铁
CuCl cupr ous chloride 氯化亚铜
CuCl2 cupr ic chloride 氯化铜
(3)两种非金属的二元化合物,根据电负性来指定元素的正氧化数和负氧化数。
电正性(电负性小的)的元素命名在先,排序规则:B、Si、C、P、N、H、S、I、Br、Cl、O、F(按照顺序谁在前,命名优先)
命名规则:含有变价非金属时,往往要用数字前缀标明其个数(当某化学物质命名时会引起歧义时,要给出原子个数)。
Eg:P2O5diphosphorus pentoxide 五氧化二磷PCl5phosphorus pentachloride 五氯化磷
N2O4dinitrogen tetroxide 四氧化二氮
NO2nitrogen dioxide 二氧化氮
CO carbon monoxide 一氧化碳
CO2carbon dioxide 二氧化碳
(4)以-ide结尾的三个特例:
OH—(hydroxide)、CN—(cyanide)、NH4—(ammonium)
Eg:NH4I ammonium iodide 碘化铵
Ca(OH)2calcium hydroxide 氢氧化钙
KCN potassium cyanide 氰化钾
(5)二元化合物得到的酸:
二元酸由氢和另外一种非金属元素构成,但不是所有的二元氢化物都是酸。
通常H在前面,接着是第二种元素符号(Eg:HCl、HBr、H2S)被认为是酸,而如CH4、NH3则不被认为是酸。
二元酸命名规则:hydro+非金属元素词干+ic acid
Eg:HCl hydro chlor ic acid 氯化氢
H2S hydro sulfur ic acid 硫化氢
二、Nomenclature of Inorganic Compounds(Ⅱ)(无机化合
物命名Ⅱ)
(一)三元化合物(ternary compounds):
1、组成:正电性基团(氢或者金属)+多原子负离子基团(只讨论其中有一个是O元素)
2、命名规则:正价基团阳离子元素符号+负价非氧元素的词干
+ite/ate
(注:ite表示负价基团中非氧元素较低的氧化态,ate表示负价基团中非氧元素较高的氧化态。
当非氧元素只有一种氧化态时,如C,用ate结尾。
)
Eg:Na2SO4 sodium sulf ate硫酸钠
Na2SO3 sodium sulf ite亚硫酸钠
K2CO3 potassium carbon ate碳酸钾
Al2(SO4)3 aluminum sulf ate硫酸铝
FeSO4 iron(Ⅱ) sulf ate / ferrous sulf ate
Fe2(SO4)3 iron(Ⅲ) sulf ate / ferric sulf ate
Cu2SO4 copper(Ⅰ) sulf ate / cuprous sulf ate
CuSO4 copper(Ⅱ) sulf ate / cupric sulf ate
(二)三元含氧酸(ternary oxy-acids):
1、组成:含氢、氧及另外一种元素(通常为非金属,少数为金属)
2、命名规则:非氢非氧元素词干+ous/ic acid
(注:1、-ic表示非氢非氧元素较高的氧化态,-ous表示非氢非氧元素较低的氧化态。
若这个非氢非氧元素只有一种氧化态时,用-ic结尾;
2、当同一系列不止含有两种含氧酸时,①氧化数高于-ic时:per-+非氢非氧元素词干+-ic acid;②氧化数低于-ous时:hypo-+非氢非氧元素词干+-ous acid)
Eg:HClO hypo chlorous acid 次氯酸
HClO2chlorous acid 氯酸
HClO3chloric acid 亚氯酸
HClO4per chloric acid 高氯酸
(三)盐(salts):
1、组成:酸中的氢原子被金属离子或者铵根离子取代。
2、命名规则:类似于三元化合物的命名:正价基团阳离子元素符号+负价非氧元素的词干+ite/ate
Eg:
(四)多于一个正离子的盐:
1、组成:一个金属取代一个H,或者不同金属取代取代两个H。
2、命名规则:
取代一个H:①:金属阳离子元素符号+氢的元素符号+盐的
结尾;②:金属阳离子元素符号+bi-+酸根中非氧元素词干+-ite(高价)/-ate(低价)
取代两个H:第一个金属元素元素符号+第二个金属元素符号+盐的结尾
Eg:
