氨基甲酸铵(NH2COONH4)是一种白色固体,易分解、易水解,可用作肥料、灭火剂、洗涤剂等。某化学兴趣小组模拟工业原理制备氨基甲酸铵,反应的化学方程式如下:2NH3(g)+CO2(g)??NH2COONH4(s) ΔH<0。(1)如图所示装置制取氨气,你所选择的试剂是___。(2)制备氨基甲酸铵的装置如图13-7所示,把氨气和二氧化碳通入四...
D、对于反应CO2(g)+2NH3(g)?CO(NH2)2(s)+H2O(g),由于CO(NH2)2为固体,故反应在达平衡之前,气体的总质量一直在变,且气体的物质的量在变,故平衡之前,气体的平均相对分子质量在变,后来不变了,则说明反应达平衡,故¯¯¯¯¯¯MM¯不再发生变化能作为此反应的平衡标志,故D正确; ...
