有A、B、C、D、 E、F六种物质，它们间的相互关系如右图所示 （连线表示能相互反应）。 已知A、B、C、D、E、F为六种常见化合物，它们的相互反应及...

分析如下:D是一种金属单质，它可能是锌或铜,如果是铜.则剩下的能与铜反应的只有AgNO3,与题目不符.所以D只能是锌;A和C反应时生成一种无色气体,所以A和C是HCl和Na2CO3中的2种,而Na2CO3不与锌反应,所以,A是Na2CO3,C是HCl;而不与HCl反应的只有BaCl2,所以F是BaCl2;剩下的2种能与锌反应的就是AgNO3,也就是E,那么B就是Ca(OH)2
小故事: 很多年前, 一个爸爸和一个妈妈想休假，所以他们决定晚上去城镇。他们叫来最信任一个人来照看孩子。当保姆来的时候，他们的连个孩子已经在床上睡着了。所以保姆只是看了看孩子是否睡的好，就坐下了。
深夜，保姆觉得无聊就想去楼下看电视。但是她看不了，因为楼下没有电视（因为孩子的父母不希望他们的孩子看太多垃圾）。她就打电话给孩子的父母，问是否可以在他们的卧室看电视，当然孩子的父母同意了。
但保姆又想要最后一个请求。她问是否可以用毯子或者衣服盖住那小丑雕像，因为那使她感到很害怕。
电话沉默了一会。
（此时爸爸在和保姆通话）
他说：带孩子离开房间……
我们将会叫警察……我们从来没有什么小丑雕像。
那小丑很可能是一个从监狱逃出来的杀人犯。
电话里沉默了一会儿。

电话里沉默了一会儿。
（正在跟保姆通话的孩子的父亲）说：带上孩子们，离开房子……我们会通知警察……我们没有一个小丑雕像……
孩子们和保姆被小丑谋杀了。
结果是，小丑是一个从监狱里逃出来的杀人犯。如果你不在5分钟内转发这个贴子，这个小丑在凌晨3点时将会拿着刀站在你的床前

一种无色气体，就只能是CO2了，A和C就是盐酸和Na2Co3中的一种，题目说C能和D反应，D是金属，A和C中能和金属反应的只能盐酸了，所以A是Na2Co3，C是盐酸，也只有锌能和盐酸反应，所以D是锌。至于E，又要和Na2Co3反应，又要和锌反应，只能是AgNO3。现在就剩下两种了，B能和盐酸反应，所以就是Ca(OH)2，最后的F就是BaCl2，这种题目就要大胆的猜想推断，最后验证一下，如果都能通就没错了
（2010?金山区一模）A、B、C、D、E、F是初中化学常见的六种物质，它们之间的转化关系如下图所示（图中“~

一种无色气体，就只能是CO2了，A和C就是盐酸和Na2Co3中的一种，题目说C能和D反应，D是金属，A和C中能和金属反应的只能盐酸了，所以A是Na2Co3，C是盐酸，也只有锌能和盐酸反应，所以D是锌。至于E，又要和Na2Co3反应，又要和锌反应，只能是AgNO3。现在就剩下两种了，B能和盐酸反应，所以就是Ca(OH)2，最后的F就是BaCl2，这种题目就要大胆的猜想推断，最后验证一下，如果都能通就没错了
（2010?金山区一模）A、B、C、D、E、F是初中化学常见的六种物质，它们之间的转化关系如下图所示（图中“~
（1）F是维持生命活动的气体单质，可知F为氧气，而B可以生成C，E也可生成C，且B和E之间可以反应，所以可以判断B为二氧化碳，而E为氢氧化钙，C为碳酸钙．（2）根据（1）可知，C为碳酸钙，B和D可以反应，且它们都是由两种元素组成的，所以可以知道D为水，所以可以写出它们反应的化学方程式．（3）A含有两种元素且能够生成水和二氧化碳，根据所学知识可以知道：碳氢化合物通过燃烧，即和氧气反应能够生成二氧化碳和水，而盐酸可以通过和碳酸盐反应生成二氧化碳和水，所以可以判断A为碳氢化合物或是盐酸，氧化铜可以和碳反应生成二氧化碳，可以和氢气反应生成水，所以A也可以使氧化铜，故可以知道A所含的元素为C、H或是H、Cl或Cu、O．故答案为：（1）O2 ；熟石灰；（2）CO2+Ca（OH）2═CaCO3↓+H2O； CO2+H2O═H2CO3；（3）C、H（或H、Cl或Cu、O）．
(1) CO 2 (2) 纯碱 (3)复分解反应 (4)Ca(OH )2 + CO 2 ==CaCO 3 ↓+ H 2 O
