exactly what you want them.

industry.   4  Popeye, the Sailorman and his girl friend Olive Oyl were born at the Max Fleischer studios

in 1933.

（1）已知：①Mg(s)+Cl₂(g)=MgCl₂(s)        △Ｈ=－641kJ·mol^－1。

②1/2Ti(s)+ Cl₂(g) =1/2TiCl₄(1) 　　 △Ｈ=－385 kJ·mol^－1。

则2Mg(s)＋TiCl₄(1)＝2MgCl₂(s)＋Ti(s)的反应热为△Ｈ=                         。

（2）已知甲醇（CH₃OH）在常温下为液体，其热值为22.7kJ•g^-1，则甲醇的标准燃烧热的热化学方程式为_______                 _____                 __。
