焓变计算H2(g)+1/2O2(g)=H2O(l) △H(298k)=-285.8kJ·mol^-1中g、l、k代表什么
焓变计算H2(g)+1/2O2(g)=H2O(l) △H(298k)=-285.8kJ·mol^-1中g、l、k代表什么
1、已知H2(g)+ 1/2O2(g) ==H2O(l) 的△rHq(298K) = -285.8kJ/mol,则H2O
在热化学方程式中,比如:H2(g)+1/2 O2(g)=H2O(l) △H=-285.8 kJ·mol-1
已知2H2(g)+O2=2H2O(l)△H=-571.6kJ/mol,CO(g)+1/2O2(g)=-285.8kJ/m
已知:CH4(g)+2O2(g)=CO2(g)+2H2O(l)△H=-890.3 KJ*mol-1H2(g)+0.5O2
焓变的计算的问题比如.H2(g)+1/2 O2(g)=H2O(l) △H=245Kj/mol如果改成这样子 2 H2(g
已知:2H2(g)+O2(g)=2H2O(l) △H=-571.6kj/mol 2h2(g)+O2(g)=2H2O(g)
H2(g)+1/2O2(g)=H2O(l) 焓变= -282.8KJ/mol CO(g)+1/2O2(g)=CO2(g)
2H2(g) + O2 (g) = 2H2O(l) △H = - 571.6 kJ/mol
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:H2(g)+1/2O2(g)==H2O(l);△H=-285.6kJ/mol C3H8(g)+5O2(g)==3C
