Calculate the enthalpy change for the combustion of 1 mole of methane (CH4) gas given that the standard enthalpy of formation of methane is -74.8 kJ/mol, and the standard enthalpies of formation for carbon dioxide (CO2) and water (H2O) are -393.5 kJ/mol and -241.8 kJ/mol respectively. The balanced chemical equation for the reaction is:CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (l)
