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
下列说法正确的是:( )
A . H2的燃烧热为571.6kJ·mol-1
B . H2SO4(aq)+Ba(OH)2(aq)=BaSO4(s)+2H2O(l)ΔH=-57.3kJ·mol-1
C . 同质量的H2(g)和CH3OH(l)完全燃烧,H2(g)放出的热量多
D . 3H2(g)+CO2(g)=CH3OH(l)+H2O(l) ΔH=+135.9kJ·mol-1
