25 ℃,101 k Pa时,强酸与强碱的稀溶液发生中和反应的中和热为-57.3 kJ/mol,辛烷的燃烧热为-5518 kJ/mol。下列热化学方程式书写正确的是( )
A.2H+(aq) + SO42-(aq)+Ba2+(aq)+2OH-(aq) = BaSO4(s)+2H2O(l);H =" -" 57.3 kJ/mol |
B.KOH(aq)+H2SO4(aq) = K2SO4(aq)+H2O(l);H=57.3kJ/mol |
C.C8H18(l)+ O2 (g)=8CO2(g)+ 92HO(g);H=5518 kJ/mol |
D.2C8H18(g)+25O2 (g)=16CO2 (g)+18H2O(1);H=5518 kJ/mol |
