Random ramblings from a guy who is too busy to have a Web site. On the bright side, you won't find any ads, pop-ups, hype, or any attempts to sell you anything at all. Furthermore, you won't find any pages divided into a hundred little boxes. And the text is so large, you don't need an electron microscope to read it. A refreshing break from reality.  Anyway, here's what I have so far as I gradually resurrect my poor neglected Web site.
PC Survival Camp
Being new to computers, or even just being a “casual user”, isn’t always fun. It's as though everybody on the planet assumes you already know all the buzzwords, and already possess all the skills necessary to use a computer.  Which is a really big assumption, when you consider that nobody was ever born knowing how to use a computer. The links below provide some quick mini-tutorials on all the skills and buzzwords that everyone else seems to assume you already know. Click on any link (underlined text) for a quick mini-lesson.

选择题
实验题

下列装置可用于某些气体的制备、干燥、性质的验证和尾气的处理(加热及夹持固定装置均略去),请回答下列问题(仪器装置可任意选用,必要时可重复选用)。              

(1)当平底烧瓶中盛装锌片,分液漏斗中盛装稀硫酸时,可验证H2的还原性并检验其氧化产物。     

①当仪器的连接顺序为A→D→B→B→C时,两次使用B装置,其中所盛的药品依次是CuO、_________。     

②检查好装置的气密性后,加热B之前必须进行的操作是______________________。   

(2)若平底烧瓶中盛装Na2O2固体,分液漏斗中盛装浓氨水,B中盛装固体催化剂,可进行氨的催化剂氧化,其反应产物为NO和H2O。     

①各仪器装置按气流方向从左到右的连接顺序为A→C→B→C,请写出B中氨的催化氧化反应方程式_________。     

②装置B中可能观察到的现象是_______________________。   

(3)若平底烧瓶中盛装MnO2分液漏斗中盛装浓盐酸,B中是纯铁粉,则可选用如图仪器装置制取纯净的FeCl3 (FeCl3遇水蒸气产生白雾)。     

①根据气流方向,从图中选择适当的仪器进行实验,则装置的连接顺序为(填字母):     A→(    )→(    )→(    )→(    )→(    );实验过程中,A、B两处均需要加热但不能同时加热,应先加热_________(填“A”或“B”),理由是_________;B中的反应发生后就可以停止加热,这说明B中的反应是_________(填“吸”或“放”)热反应。     

②设计一种方案,证实实验结束后,B中固体中仍存在一定量的铁单质________________。
