C(s)+O2(g)===CO2(g)和C(s)+1/2O2(g)===CO2(g)
C(s)+O2(g)===CO2(g)和C(s)+1/2O2(g)===CO2(g)
C(s)+O2(g)=CO2(g)是什么反应?
C(s)+O2(g)==CO2(g)+Q1 C(s)+(1/2)O2(g)==CO(g)+Q2 比较Q1与Q2的大小
已知:C(s)+1/2O2(g)=CO(s)▲H=-110.35kj/mol C(s)+O2(g)=CO2(g)▲H=-
化学反应的△H前者大于后者的是?前者:C(s)+O2(g) = CO2(g) △H1 后者:C(s)+1/2O2(g)=
怎么比较C(s)+O2(g)=CO2,△H1,C(s)+1/2O2(g)=CO(g)△H2 的反应热大小
已知热化学方程式CaCO3(S)=CaO(s)+CO2(g)-178.3kj,C(s)+O2(g)=CO2+395kj
1.c(s)+o2(g)=co2(g);△H=-393.5kj/mol
C(s)+O2(g)=CO2(g) ΔH=-393.5 kJ/mol
已知如下两个热化学方程式:C(s)+O2(g)→CO2(g) H=-393.5KJ,2H2(g)+O2(g)→2H2O(
C【s】+1/2O2【g】=CO【g】
热化学方程式的比较C(g)+O2(g)=CO2(g) △H1 C(g)+1/2O2(g)=CO(g) △H2这两条化学反
