When Penny Morrissey and her family moved into their new house, they were surprised to find that those other people had left something behind. It stood against the 1 and faced the front door. It was one clock called a grandfather clock.
The 2 of the silent clock stood still. For a few moments, the whole family stood and 3 it.
Penny’s mother said, “We just need to start it up again. It’s 5:31 now. In about a half hour, we will hear it chime six times.” They all went into the 4 , and Penny’s mom and dad cooked supper while the kids did their homework. Now and then they looked up at the clock and 5 the six chimes.
When the kitchen clock said 6 o’clock, they were 6 at what they heard. The grandfather clock’s chimes 7 lovely, but there were only five! Puzzled, they all looked at 8 .
“Did you hear what I heard?” Penny asked.
“Let’s go and look at the clock,” said her sister Clara. It said 5 o’clock! It had gone backwards!
Just then, they heard the sound of an engine. They looked out the window and saw a
九年级化学下册知识点(鲁教版)
鲁教版九年级化学下册中考知识点 第七单元常见的酸和碱 第一节酸及其性质 一、如何识别酸 1、电离 （1）定义：物质溶于水后离解成自由移动的离子的过程 （2）、溶液导电的原因：溶液中存在自由移动的离子 （3）、电离方程式：（溶于水） ①HCl=H++Cl- ②H2SO4=2H++SO42- 2、由①②得：酸：电离时生成的阳离子全部是氢离子的化合物。例：硝酸、碳酸、硫酸、盐酸、醋酸等 二、酸的性质 1、盐酸和硫酸的物理学性质（浓） （1）盐酸（物理性质） 无色、透明有刺激性气味的液体，密度比水大，打开浓盐酸瓶塞，瓶口出现白雾，说明浓盐酸具有挥发性，工业盐酸因具有杂质而略显黄色。 （2）、硫酸（物理性质） ①无色、粘稠油状的液体，密度比水大，具有吸水性，因此可用作某些气体的干燥剂。 ②稀释浓硫酸：把浓硫酸沿玻璃棒慢慢引流到水里，切不可将水注入浓硫酸。 2、盐酸和硫酸的化学性质（稀） 因为盐酸和硫酸在溶液中都能电离出氢离子，所以化学性质相似。 （1）酸与指示剂的作用 酸能使紫色的石蕊变成红色，使无色酚酞不变色，使蓝色石蕊试纸变成红色 （2）酸+金属——盐+氢气 ③Na2CO3=2Na++CO32- ④CuSO4=Cu2++SO42- 由③④得：盐：电离时生成金属离子和酸根离子的化合物。例：氯化钠、硫酸铜、碳酸钠等 A、化学方程式
Mg+2HCl=MgCl2+H2↑ Fe+2HCl=FeCl2+H2↑现象：铁的表面有气泡产生，溶液有无色变成浅绿色 Zn+2HCl= ZnCl2+H2↑ 2Al+6HCl=2AlCl3+3H2↑ Mg+H2SO4=MgSO4+ H2↑ Fe+H2SO4=FeSO4+H2↑现象：铁的表面有气泡产生，溶液有无色变成浅绿色 Zn+H2SO4= ZnSO4+H2↑ 2Al+3H2SO4=Al2(SO4)3+3H2↑ B、用途：验室制氢气 （3）、酸+金属氧化物——盐+水 ①化学方程式 Fe2O3+6HCl=2FeCl3+3H2O 现象：铁锈消失，溶液有无色变为黄色 Fe2O3+3H2SO4=Fe2(SO4)3+3H2O现象：铁锈消失，溶液有无色变为黄色 ②用途：金属除锈 （4）、酸+盐——另一种酸+另一种盐 ①化学方程式 2HCl+Na2CO3=2NaCl+H2O+CO2↑用于检验碳酸根离子 HCl+AgNO3=AgCl↓+HNO3用于检验氯离子 H2SO4+BaCl2=BaSO4↓+2HCl用于检验硫酸根离子 ②实例：检验一瓶无色溶液中含有碳酸根离子 取无色溶液少许注入试管，向试管中加入稀盐酸，将产生的气体通入澄清石灰水，如果石灰水变浑浊，证明产生二氧化碳，因此证明原溶液中含有碳酸根。 （5）、复分解反应 ①定义：两种化合物在溶液中互相交换成分，生成另外两种化合物的反应。中和反应是复分解反应中的一种。 ②复分解反应发生的条件：生成沉淀、气体、水 第二节碱及其性质 一、如何识别碱 （1）电离方程式： ⑤NaOH=Na++OH- ⑥Ca(OH)2=Ca2++2OH-

鲁教版九年级化学下册教学计划
九年级化学(鲁教版)下册教学计划 一、指导思想 以国家颁布的《全日制义务教育化学课程标准》确定的培养目标为依据，结合初中毕业生学业考试复习指南（化学），强化学生基础知识，训练学生思维方式，培养学生实验技能，提升学生应试水平，贯穿“从生活走向化学，从化学走向社会”理念，突出化学知识与生活、社会、科技之间的联系，拓展学生化学思维。 二、教学内容 鲁教版九年级化学下册第7～11章。 三、学生分析 本人所教化学学科有两个班，大部分学生没有养成良好的学习习惯、行为习惯，学习成绩较差，对问题的分析能力、计算能力、实验操作能力存在严重的不足，尤其是所涉及知识拓展和知识的综合能力等方面不够好，学生反应能力弱。以上情况主要原因是学生在九年级前各科成绩都较差，没有学会如何分析问题，学习方法不对，且不会进行知识的梳理，对所学化学知识不能进行归纳系统化，导致学生掉队，同时学生面临毕业和升学的双重压力等，致使许多学生产生了厌学心理。教师要做好每一个学生的工作，使他们在各自原有的基础上不断发展进步。 四、教材分析 现行教材体系的第一个特点是分散难点，梯度合理，又突出重点。以学生生活中离不开的水、空气、溶液，以及碳等引入，学习元素和
化合物知识，同时有计划地穿插安排部分基本概念，基本理论和定律。这样使教材内容的理论与实际很好地结合，有利于培养学生运用化学基本理论和基本概念解决生活和生产中常见的化学问题的能力，还可以分散学习基本概念和基本理论，以减轻学习时的困难。为了有利于教师安排教学和便于学生学习和掌握，每章教材的篇幅力求短小，重点较突出。 第二个特点，突出了以实验为基础的，以动手操作能力要求，每一块中都有有许多学生实验和实验探究，同时又注意了学生能力的培养。 五、目标任务 1.让化学知识联系生产、生活、自然、社会现象等实际，使学生学以致用。 2.使学生学习一些常见金属材料、溶液及酸碱盐的基础知识，掌握部分化学实验和化学计算基本技能，并了解化学在生产中的实际应用。 3.继续激发学生学习化学的兴趣，培养学生科学严谨的态度和科学的方法。培养学生动手和创新精神。使学生初步运用化学知识来解释或解决简单的化学问题，逐步养成自己动手操作的能力、观察问题和分析问题的能力。 4.针对中考新动向，把握中考改革的方向，培养学生适应中考及答题的各种技能技巧。 5.重视基础知识和基本技能，注意启发学生的智力，培养学生的

鲁教版九年级化学下册碱及其性质教案
《第二节几种常见的碱》教案 教学目标 知识与技能 1、知道常见氢氧化钠、氢氧化钙主要的物理性质和用途。 2、认识氢氧化钠、氢氧化钙的腐蚀性及使用的安全注意事项。 3、能由探究实验知道碱的相似化学性质。 过程和方法 1、运用实验、观察等方法进行探究，并比较、归纳和概括氢氧化钠和氢氧化钙的性质。 2、能应用氢氧化钠和氢氧化钙的性质解释或解决一些实际问题。 情感态度与价值观 1、通过对氢氧化钠和氢氧化钙的性质的探究，保持和增强对化学现象的好奇心和探究 欲，发展学习化学的兴趣。 2、通过讨论、实验进一步发展善于合作、勇于实践的科学精神。 教学重点 氢氧化钠、氢氧化钙的物理性质与用途以及碱的相似化学性质。 教学难点 氢氧化钠、氢氧化钙与非金属氧化物反应的化学方程式。 教学过程 创设问题情境：魔术表演引入：“清水变牛奶”，让学生通过已知的化学知识解释，并 写出相应的化学反应方程式。再表演“不吹自大的气球”。 提问：气球为什么不吹自大哪？想知道其中的奥秘吗？通过今天的学习就能解释出其中 缘由。今天外面学习的内容是——常见的碱。 首先来认识氢氧化钠，让学生观察氢氧化钠固体。 提问：如何取用氢氧化钠，能直接用手拿吗？为什么？引导学生观察被氢氧化钠腐蚀的 鸡爪。正是由于氢氧化钠的强的腐蚀性，由此我们俗称氢氧化钠为？如果不慎将氢氧化钠沾 到皮肤上该如何处理呢？引导学生观察，然后互相交流。 观察、思考并对已学知识的回顾Ca（OH）2+CO2=CaCO3↓+H2ONaOH有强烈的腐蚀性在使用NaOH时必须十分小心。
进行化学药品的安全知识教育。激发学生提出问题和研究问题的热情。 将氢氧化钠固体放到水中溶解，让学生触碰试管外壁，让学生知道氢氧化钠固体溶解放 热的现象。 氢氧化钠放入水中溶解放热，把它放在空气中又会如何？用两只表面皿把氢氧化钠固体 颠换，让学生观察氢氧化钠不久就沾在表面皿上，从而得知氢氧化钠会潮解。 提问：潮解是不是化学反应呢？为什么？ 氢氧化钠还有哪些用途呢？引导学生阅读氢氧化钠的用途。其实氢氧化钠还可以做叶脉 书签，课本有制作叶脉书签的家庭小实验。 认识完氢氧化钠，我们再来认识另外一种常见的碱——氢氧化钙。在检验二氧化碳时用到的澄清石灰水就是氢氧化钙的水溶液提问：同学知道氢氧化钙是如何制取的吗？它俗称什么？ 实验展示：氧化钙和水反应，并要求学生写出化学方程式。 提问：除了氢氧化钠、氢氧化钙之外，常见的碱还有哪些，并写出他们的化学式？这些 碱都具有哪些相似的化学性质呢？我们通过化学实验进一步进行探究。 请一位学生来完成实验，观察学生的实验操作是否规范并进行相应指导。 实验：NaOH、Ca（OH）2溶液中分别滴加石蕊试液和酚酞试液。 引导学生归纳实验的结论。 结论：（1）碱溶液能使紫色石蕊试液变蓝色，无色酚酞试液变红色。 提问：细心的同学应该发现两只试管内的溶液颜色深浅有所不同，这是什么原因呢？这个问题我们留作课后思考。 氢氧化钙可做建材，利用到它什么性质呢？同学们能写出相应的化学反应方程式吗？氢 氧化钠密封保存仅仅是因为潮解的原因吗？展示一瓶氢氧化钠溶液，提示学生注意观察。提问：氢氧化钠溶液试剂瓶口有一些白色固体，请同学分析一下白色固体可能是什么？其中又 涉及到什么化学反应呢？注意把碱的一些性质联系起来。 上面两个化学反应有什么共同之处？三氧化硫与碱的反应与上面两个反应相似，试写出三氧化硫与氢氧化钠的化学方程式。 结论：（2）碱溶液能与某些非金属氧化物反应。 问题：硫酸厂排放的废气中含有二氧化硫，为了周围居民的安全，利用我们已知的化学知识帮居民解决这个问题。 通过刚才的学习，谁能揭晓“不吹自大的气球”的秘密？注意联系一些已学的物理知识
