高中化学错题精集1
高中化学错题集例题1、在某100ml的混合液中,硝酸和硫酸的物质量浓度分别是0.4mol/L,0.1mol/L,向该混合液中加入 1.92g铜粉,加热,待充分反应后,所得溶液中铜离子物质量浓度是(mol/L):A 0.15B 0.225C 0.35D 0.45容易错选答案为A错误原因:根据反应:3Cu + 8HNO3 = 3Cu(NO3)2 + 2NO + 4H2O,题目中给出的硝酸的物质的量为0.04mol,因此,参与反应的铜的物质的量为0.015mol,因此答案为A。
解题时忽略溶液中仍然存在H+,在该条件下,生成的Cu(NO3)2中的硝酸根离子要和铜继续反应。
正确解答思路为:根据3Cu + 8H+ +2NO3- ==3Cu2+ +2NO +4H2O3 8 2 30.03 0.06 0.04 XX=3*0.6/8=0.0225mol因此,铜离子浓度为0.225MOL/L例题2、为了测定某铜银合金成分,将30g合金完全溶于80ml13.5mol/L的浓硝酸中,待反应完全后,收集到6.72L气体(标况),并测得溶液中H离子浓度是1mol/L.假设反应后溶液体积仍为80ml,求合金中银的质量分数.错解:假设银的质量分数为X,则:Ag + 2HNO3 = AgNO3 + NO2 + H2O30X /108 60X/108 30X/108Cu + 4HNO3 = Cu(NO3)2 +2NO2 +2H2O30(1-X)/64 120(1-X)/64 60(1-X)/64根据气体体积关系有: 30X/108 + 60(1-X)/64=0.3,解得X或根据HNO3量的关系有:60X/108 +120(1-X)/64=0.08*(13.5-1),解得X错误原因:没有考虑到硝酸浓度的变化。
正确解答为:假设铜、银的物质的量依次为X、Y,则有64X+108Y=30(固体质量关系)2X+Y+0.3=0.08*(13.5-1)(硝酸中N的守恒),从而得到X=0.1mol,即银的质量为23.6g 质量分数为78.7%例题3、标准状况下,往100mL 0.2mol/L的FeBr2溶液中通入一定体积的Cl2,充分反应后,溶液中有50%的Br-被氧化。

错题集1-牛客
错题集1-⽜客⼀、下⾯哪⼀个不是JavaScript的数据类型?A.StringB.BooleanC.IntegerD.Undefined答案:C解题思路:JavaScript的数据类型分为两种:原始类型(即基本数据类型)和对象类型(即引⽤数据类型):基本类型:String、Number、Boolean、Null、Undefined、Symbol引⽤类型:Object、Array、FunctionInteger是整⾏的意思⼆、HTML5 中不再⽀持下⾯哪个元素?A.<q>B.<ins>C.<menu>D.<font>答案:D解题思路:HTML废除的元素1、能⽤css代替的元素basefont、big、center、font、s、strike、tt、u。
这些元素纯粹是为画⾯展⽰服务的,HTML5中提倡把画⾯展⽰性功能放在css中统⼀编辑。
2、不再使⽤frame框架。
frameset、frame、noframes。
HTML5中不⽀持frame框架,只⽀持iframe框架,或者⽤服务器⽅创建的由多个页⾯组成的符合页⾯的形式,删除以上这三个标签。
