I know the answer is 3 ml. I also know that it' s … Thermochemical Equation . When methane gas is combusted heat is released making the reaction exothermic . Specifically the combustion of 1 mol of methane releases 890.4 kilojoules of heat energy. This information can be shown as part of the balanced equation . Which of the following is a correctly written thermochemical equation ? C3H8( g ) + O2( g ) → CO2( g ) + H2O(l) ΔH = 2 220 kJ/mol. How does a phase change affect a thermochemical equation ? It can affect the ΔH value. For the reaction CH4 ( g ) + 2O2 ( g ) → CO2 ( g ) + 2H2O (l) ΔH = -890 kJ what will be the change in enthalpy when 3 moles of ... Wed Oct 18 2017 · Of course the enthalpy is quoted per moles of reaction of written. And another way I could represent this is as..... # Al_2O_3 ( s ) +1676*kJ rarr 2Al( s ) + 3/2O_ 2 ( g )# The positive sign of the quoted e...
