（6分）实验室常用加热铵盐和碱的固体混合物的方法制取氨气。
根据下图回答问题：
（1）实验室制取氨气的发生装置为 （填序号），该反应的化学方程式为 。
（2）下列气体可以用与氨气相同的收集装置收集的是 （填序号）。
A． H2 B． CO2
（1）A 2NH4Cl + Ca(OH)2 =加热= CaCl2 + 2NH3 + 2H2O （2）A
（1）实验室制取氨气是固固反应，反应需要加热，所选发生装置为A，
该反应的化学方程式：2NH4Cl + Ca(OH)2 
CaCl2 + 2NH3↑+2H2O
（2）氨气密度比空气小，易溶于水，收集时向上排气法收集，选项中氢气也用向上排气法收集，故选A。
