Hi guys can you please check if this is right...thanks in advance
The heat released by the reaction 2C + 2H2 = CH4 is 74.8kJ/mol. Using this information and a table of standard enthalpy of formation values, determine the heat of combustion for the burning of methane to form CO2 and H2O(g).
C02 = -393.3 kJ/mol
H20 = -286.2 kJ/mol
2C + 2H2 = CH4 H1 = 74.8
C + O2 = CO2 H 2= -393.3
H2 +1/2 O2 = H2O H3 = -286..2
CH4 +3O2 = CO2 + 2H2O -H1 + H2 +2H3 = -1040.5 Kj/mol
