下列说法正确的是
已知：2H₂(g)＋O₂(g)=2H₂O(l)           ΔH＝－571.6 kJ·mol^－1
2CH₃OH(l)＋3O₂(g)=2CO₂(g)＋4H₂O(l)    ΔH＝－1452 kJ·mol^－1
H^＋(aq)＋OH^－(aq)=H₂O(l)               ΔH＝－57.3 kJ·mol^－1

A．H2(g)的燃烧热为571.6 kJ·mol^－1

B．同质量的H2(g)和CH3OH(l)完全燃烧，H2(g)放出的热量多

C．H2SO4(aq)＋Ba(OH)2(aq)==BaSO4(s)＋H2O(l)ΔH＝－57.3 kJ·mol^－^1

D．3H2(g)＋CO2(g)=CH3OH(l)＋H2O(l)ΔH＝＋135.9 kJ·mol^－^1
