已知H+(aq) + OH-(aq) = H2O (l) ;△H =" -57.3" KJ/mol . 则下列热化学方程式正确的是
A.CH3COOH(aq) + NaOH(aq) = CH3COONa (aq) + H2O(l); △H=-57.3KJ/mol |
B.H2SO4(aq) + Ba(OH)2(aq) = BaSO4 (s) + 2 H2O(l) ; △H= -114.6KJ/mol |
C.HCl(aq) + NaOH(s) =" NaCl" (aq) +H2O(l) ; △H= -57.3KJ/mol |
D.HI(aq) + KOH(aq) =" KI(aq)" + H2O(l) ;△H= -57.3KJ/mol |
