2015-2016学年黑龙江省绥化市肇东一中高一下学期期中化学试卷
①2HI(g)=H2(g)+I2(g)△H1
②SO2(g)+I2(g)+2H2O(g)=H2SO4(l)+2HI(g)△H2
③H2SO4(l)=H2O(g)+SO2(g)+ O2(g)△H3
④2H2O(g)=2H2(g)+O2(g)△H4
△H4与△H1、△H2、△H3之间的关系是:△H4=.
①N2(g)+2O2(g)=N2O4(l)△H1=﹣19.5kJ•mol﹣1
②N2H4(l)+O2(g)=N2(g)+2H2O(g)△H2=﹣534.2kJ•mol﹣1
6C(s)+5H2(g)+3N2(g)+9O2(g)=2C3H5(ONO2)3(l)△H1
2 H2(g)+ O2(g)= 2H2O(g)△H2
C(s)+ O2(g)=CO2(g)△H3
则反应4C3H5(ONO2)3(l)= 12CO2(g)+10H2O(g) + O2(g) +6N2(g)的△H为( )
