25 ℃、101 kPa下,碳、氢气、甲烷和葡萄糖的燃烧热依次是ΔH=-393.5 kJ·mol-1、ΔH=-285.8 kJ·mol-1、ΔH=-890.3 kJmol-1、ΔH=-2 800 kJ·mol-1,则下列热化学方程式正确的是 ( )。
A.C(s)+O2(g)===CO(g) ΔH=-393.5 kJ·mol-1 |
B.2H2(g)+O2(g)===2H2O(l) ΔH=-571.6 kJ·mol-1 |
C.CH4(g)+2O2(g)===CO2(g)+2H2O(g)ΔH=-890.3 kJ·mol-1 |
D.C6H12O6(s)+3O2(g)===3CO2(g)+3H2O(g)ΔH=-1 400 kJ·mol-1 |
