中考典型易错题举例分析
2. —_______ do you _______ about spring?
—The flowers and the green trees.
A. How, like B. How, think C. What, think D. What,
like
【解析】此题陷阱选项为A或B或C。这是由于忽略语境造
成的。由答语The flowers and the green trees. 可知,所
问的是“你喜欢春天的什么?”而不是“你觉得春天怎么
样?”。正确答案为D。
1. It is _______ outside. Let’s put on our raincoats and
go out, Tom.
A. cold B. hot C. sunny D. rainy
【解析】此题易误为A。因为这里有个put on短语,如果
不注意raincoats这个词那就很可能草率地选择A。
raincoats是“雨衣”的意思,而不是一般的衣服,那么不
是因为外面“冷”,而是因为“下雨”才穿“雨衣”。正确
答案为D。
3. —What’s your sister like?
—_______.
A. She is a worker B. She likes p

精选中考化学易错题专题复习计算题含答案解析
一、中考初中化学计算题
1.硫酸铜溶液对过氧化氢的分解有催化作用。取一定质量8.5%的过氧化氢溶液倒入烧杯中,加入一定质量15%的硫酸铜溶液,过氧化氢完全分解。有关实验数据如下表所示(不考虑气体在水中的溶解)。请计算:
(1)生成氧气的质量为___________g。
(2)反应后烧杯中溶液溶质的质量分数为____________。(写出计算过程,结果精确到0.1%)【答案】0.8 2.2%
【解析】
【分析】
【详解】
(1)根据质量守恒定律,氧气的质量=(60g+3.3g)﹣62.5g=0.8g;
(2)根据题意,过氧化氢完全分解后,溶液中的溶质是硫酸铜,因为硫酸铜是催化剂,反应前后质量不变,所以溶液中硫酸铜的质量=3.3g×15%=0.495g,只要求出反应后溶液的质量就可求出反应后溶液中溶质的质量分数。
设过氧化氢溶液中含H2O2的质量为x
2222
2H O=2H O+O
6832
x0.8g
↑
68x
=
320.8g
解得x=1.7g,
则过氧化氢溶液的质量=1.7g÷8.5%=20g,
反应后烧杯中溶液溶质的质量分数=
0.495g
100%
20g+3.3g-0.8g
?=2.2%。
答:(1)生成氧气的质量为0.8g。
(2)反应后烧杯中溶液溶质的质量分数为2.2%
