对于热方程式说法正确的是：

A．中和热ΔH＝－57.3 kJ·mol^－1,, 则2H^＋(aq)＋(aq)＋Ba^2＋(aq)＋2OH^－(aq)===BaSO₄(s)＋2H₂O(l)　△H＝－114.6 kJ·mol^－1

B．将0.5 molN₂和1.5 mol H₂于密闭容器生成NH₃(g)，放热19.3 kJ，方程式为：

N₂(g)+3H₂(g)2NH₃(g)△H="—38.6" kJ·mol^—1

C．标准状况：H₂(g)＋F₂(g) ==="2HF(g)" △H＝－270kJ/mol，

D．氨氧化：4NH₃(g)＋5O₂(g) ===4NO(g)＋6H₂O(g)△H＝－1025 kJ/mol
