25℃、101 kPa下,碳、氢气、甲烷和葡萄糖的燃烧热依次是△H=" -" 393.5 kJ/mol、△H=" -285.8" kJ/mol、△H=" -" 890.3 kJ/mol、△H=" -" 2 800 kJ/mol,则下列热化学方程式正确的是
A.C(s)+O2(g)="CO(g)" △H="" - 393.5 kJ/mol |
B.2H2(g)+O2(g)=2H2O(l)△H=" -" 571.6 kJ/mol |
C.CH4(g)+2O2(g)=CO2(g)+2H2O(g)△H=" -" 890.3 kJ/mol |
D.C6H12O6(s)+3O2(g)=3CO2(g)+3H2O(g)△H=" -" 1400 kJ/mol |
