determine the mass of water formed when 12.5L NH3(at 98K and 1.5 atm) is reacted with 18.9L of O2 (at 323K and 1.1 atm)
题目意思:12.5L氨气(98K,1.5个大气压)和18.9L氧气(323K,1.1个大气压)生成多少重量的水?
1.用公式PV=nRT分别算出氨气,氧气的物质的量n1 ,n2(R=8.13kJ/Mol/K,P,V,T为已知量,V要变成已m3为单位.
2.化学反应 4 NH3+ 5 O2 = 4 NO + 6 H2O
4 5 n
n1 n2
按比例关系判断NH3 ,O2 何者过量 以量少者按反应比例计算出H2O 的物质的量 又m=Mn 即可计算出H2O的质量
12.5L氨气(98K,1.5大气压)和18.9L氧气(323K,1.1个大气压)生成多少水
