25 ℃、101 kPa下，碳、氢气、甲烷和葡萄糖的燃烧热依次是393．5 kJ·mol^－1、285．8 kJ·mol^－1、890．3 kJ·mol^－1、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(g)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(l)ΔH＝－1 400 kJ·mol^－1
