Answer 1

常见的热化学方程式如下：

1、CaCO3(s)+==CaO(s)+CO2(g);△H=+1777kJ/mol

2、C(石墨)+O2(g)===CO2(g);△H=-393.51kJ•mol-1

3、C(金刚石)+O2(g)===CO2(g);△H=-395.41kJ•mol-1

4、C(石墨)===C(金刚石);△H=+1.9kJ•mol-1

5、NaOH(aq)+HCl(aq)=NaCl(aq)+H2O(l);△H=-57.3kJ/mol

6、C(s)+O2(g)==CO2(g);△H=-110.5kJ/mol

7、CO(g)+1/2O2(g)==CO2(g);△H=-283.0kJ/mol

8、H2(g)+1/2O2(g)==H2O(g);△H=-241.8kJ/mol

9、N2H4(g)+O2(g)==N2(g)+2H2O(g);△H=-534kJ/mol

10、S(s)+O2(g)==SO2(g);△H=-297kJ/mol

11、FeS2(s)+11/4O2(g)==1/2Fe2O3(s)+2SO2(g);△H=-853kJ/mol

12、SO2(s)+1/2O2(g)==SO3(g);△H=-98.3kJ/mol

13、3H2(g)+N2(g)==2NH3(g);△H=-92.2kJ/mol

14、2O2(g)+N2(g)==2NO2(g);△H=+68kJ/mol

15、O2(g)+N2(g)==2NO(g);△H=-kJ/mol

16、NaOH(aq)+1/2H2SO4(aq)=1/2Na2SO4(aq)+H2O(l);△H=-57.3kJ/mol
