阅读理解。

                                                                       A clever man

     A gentleman met Bill one day. The rich man said, "They say you are very clever, but I don't believe it. Bill

said with a smile, "I am not clever. Instead, you are very stupid."

    The gentleman became very angry. Bill said, "Please don't be angry, sir."

    "If you don't believe what I said, let me ask you one question. If you have a group of cows, and I give you

another group, then how many groups of cows do you have?"

    "Why, that's the easiest question in the world! One and one is two, I have two groups of cows," Bill laughed

and said. "You are wrong, sir. Two groups put together are still one group. That is the easiest question in the

world."

火柴头上通常含有氯酸钾、二氧化锰、硫等物质．某研究性学习小组进行火柴头中有关物质的实验探究．

（1）检验火柴头中含有硫将两根火柴放在如图甲所示实验装置中漏斗下面，用一根燃着的火柴点燃它，慢慢拉动注射器活塞抽气，让火柴燃烧产生的气体通过稀品红溶液，观察到品红溶液褪色．

①燃烧产生的气体中一定含有______．

②可用于替代试管中品红溶液的试剂有______（填标号）．

A．稀高锰酸钾酸性溶液 B．饱和石灰水

C．稀溴水D．烧碱溶液

③某同学提出用图乙所示方法进行实验更为简便．他的操作是：

i．当图乙中所示火柴头燃烧完时，立即移出火柴；

ii．______．

（2）证明火柴中的氯元素是以氯酸钾的形式存在，而不是以氯化钾的形式存在，请完成下列操作：

①取3～4根火柴，摘下火柴头，浸入水中，片刻后，取少量溶液于试管中，加入少量的硝酸银溶液，没有白色沉淀生成；

②再往上述溶液中加入稀硝酸和NaNO₂溶液，观察到有白色沉淀生成．反应的离子方程式是______；

③将燃尽的火柴头浸泡在少量水中，片刻后取少量溶液于试管中，滴加AgNO₃和稀硝酸，可观察到白色沉淀产生，说明将燃尽的火柴头浸泡在少量水中，会有______物质被浸出，说明火柴头燃烧时其中含有的______转化为该物质．

（3）测定火柴头中KClO₃的含量主要实验步骤如下：

（i）刮取火柴头，小心研碎，称得质量为2.45g；

（ii）用适量蒸馏水充分浸泡后过滤、洗涤残渣；

（iii）往装有滤液和洗涤液的烧杯中加入过量的NaNO₂溶液、AgNO₃溶液和稀硝酸，搅拌，充分反应后，过滤、洗涤沉淀；

（iv）干燥沉淀物，称得其质量为1.435g．

①反应中NaNO₂、AgNO₃均需要过量的原因是______；

②实验测得火柴头中KClO₃的质量分数为______；

③如果第ii步中未洗涤沉淀残渣，测得KC1O₃的质量分数将______（填“偏大”、“偏小”、或“无影响”，下同）；如果第Ⅲ步中未洗涤AgCl沉淀，测得KClO₃的质量分数将______．
