2015-2016学年内蒙古包头市北重五中高二上学期期末化学试卷（理科）
①H2S(g)＋ O2(g)=SO2(g)＋H2O(g) ΔH1
②2H2S(g)＋SO2(g)= S2(g)＋2H2O(g) ΔH2
③H2S(g)＋ O2(g)=S(g)＋H2O(g) ΔH3
④2S(g)=S2(g) ΔH4
则ΔH4的正确表达式为( )
①C(s) + H2O(g)=CO(g)+H2(g) ΔH1=a kJ•mol-1
②CO(g) + H2O(g)=CO2(g)+H2(g) ΔH2=b kJ•mol-1
③CO2(g)+3H2(g)=CH3OH(g)+H2O(g) ΔH3 =c kJ•mol-1
④2CH3OH(g) =CH3OCH3(g)+H2O(g) ΔH4=d kJ•mol-1
