已知的 H2(g)+0.5O2(g)==H2O(g) △H=-41
已知的 H2(g)+0.5O2(g)==H2O(g) △H=-41
已知:2H2(g)+O2(g)=2H2O(l) △H=-571.6kj/mol 2h2(g)+O2(g)=2H2O(g)
已知:CH4(g)+2O2(g)=CO2(g)+2H2O(l)△H=-890.3 KJ*mol-1H2(g)+0.5O2
已知2H2(g)+O2(g)=2H2O(l);△H=-571.6kJ/mol,C3H8(g)+5O2(g)=3CO2(g
求详解(自学没基础)已知:h2o(l)=h2o(g);△H=Q1 kj/mol2h2o(g)=2h2(g)+o2(g);
已知:2H2(g)+O2(g)═2H2O(g)△H=-483.6kJ•mol-1 H2(g)+12O2(g)═H2O(l
已知:2H2(g)+O2(g)=2H2O(l) △H=571.6kj/mol
已知2H2(g)+O2(g)=2H2O(g)△H=-484kj/mol 2H2(g)+O2(g)=2H2O(l)△H=-
已知下列热化学方程式:2H2(g)+O2(g)=2H2O(g)△H=-484kJ/mol,H2(g)+12O2(g)=H
已知热化学方程式:H2O(g)=H2(g)+12O2(g)△H=+241.8kJ/mol;H2(g)+12O2(g)=H
已知H2(g)+1/2O2(g) =H2O(g)H=-241.8kj/mol 下列说法不正确的是 A H2然烧放出的热量
已知:2H2(g)+O2(g)=2H2O(l)△H=-571.6KJ/mol,2H2O=2H2(g)+O2(g) △H=
