已知2H2(g)+O2(g)=2H2O(1)^H=_571.6kj·mol·-1CO(g)+1/2O2(g)==CO2(g)&H=-283kj.mol-1某H2和CO的混合气体
你这个问题是不是没写明白?理一下,再发
再问: 已知2H2(g)+O2(g)=2H2O(1)^H=_571.6kj·mol·-1CO(g)+1/2O2(g)==CO2(g)&H=-283kj.mol-1某H2和CO的混合气体完全燃烧时放出113.74kj热量,同时生成3.6g液态水,求原混合气体中H2和CO的物质的量
再问: 已知2H2(g)+O2(g)=2H2O(1)^H=_571.6kj·mol·-1CO(g)+1/2O2(g)==CO2(g)&H=-283kj.mol-1某H2和CO的混合气体完全燃烧时放出113.74kj热量,同时生成3.6g液态水,求原混合气体中H2和CO的物质的量
已知2H2(g)+O2(g)=2H2O(1)^H=_571.6kj·mol·-1CO(g)+1/2O2(g)==CO2(
已知;2H2(g)+O2(g)=2H2O(l)△H=-571.6kJ•mol-1 CO(g)+1/2O2(g
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
H2(g)+1/2O2(g)=H2O(l) 焓变= -282.8KJ/mol CO(g)+1/2O2(g)=CO2(g)
已知H2+1/2O2=H2O(l) 焓变= -285.83KJ/mol,CO(g)+1/2O2(g)=CO2(g) 焓变
求详解.已知CH4(g)+2O2(g)=CO2(g)+2H2O(l);ΔH=-890 kJ·mol-1,现有CH4和CO
H2(g)+1/2O2(g)==H2O(g) △H=+242KJ/mol , 2H2(g)+O2(g)==2H2O(g)
已知热化学方程式 C(g)+O2(g)=CO2(g); △H=-393.5kJ/mol H2(g)+1/2O2(g)=h
已知2H2(g)+O2(g)=2H2O(l);dertaH=—571.6kj/mol,CO(g)+1/2O2(g)=CO
已知热化学方程式:H2O(g)=H2(g) O2(g) △H= 241.8kJ·mol-1; H2(g) O2(g)=H
已知2H2(g)+O2(g)==2H2O(l) △H=-571.6KJ/mol CO(g)+1/2O2(g)==CO2(
