(1)生成水煤气的热化学方程式是                          ;

(2)合成氨需要在较大的压力下进行的原因是                          ;

(3)温度过高或过低对合成氨的影响是                          ;

(4)由氨生成HNO3的各步反应的化学方程式是                          ;

(5)某化肥厂由NH3制备HNO3,进而生产硝铵(NH4NO3)。假设由氨氧化生成HNO3的总产率是85%,而HNO3和NH3完全反应生成NH4NO3。列式计算:

①从NH3制取NH4NO3过程中,用于中和硝酸所需的氨占总的氨消耗量的分数;
