胶状液氢(主要成分是H2和CH4)有望用于未来的运载火箭和空间运输系统。实验测得101 kPa时,1 mol H2完全燃烧生成液态水,放出285.8 kJ的热量;1 mol CH4完全燃烧生成液态水和CO2气体,放出890.3 kJ的热量。下列热化学方程式书写正确的是( )
A．2H2(g)+O2(g)2H2O(l) ΔH="-285.8" kJ/mol
B．CH4(g)+2O2(g)CO2(g)+2H2O(l)ΔH="-890.3" kJ/mol
C．CH4(g)+2O2(g)CO2(g)+2H2O(g)ΔH="-890.3" kJ/mol
D．CH4(g)+2O2(g)CO2(g)+2H2O(l)ΔH="+890.3" kJ/mol
2H2O(l) ΔH="-285.8" kJ/mol
