The standard enthalpies of formation, at 25.00 °C, of

The standard enthalpies of formation, at 25.00 °C, of methane (CH4(g)), water (H₂O(1)), and carbon dioxide (CO2(g)) are, respectively, -74.6 kJ/mol, -285.8 kJ/mol, and -393.5 kJ/mol. Calculate the amount of heat released (in kJ) during the combustion of 15.86 L of methane under a constant pressure of 1.000 atm at 25.00 °C (N.B. combustion is the reaction with molecular oxygen to produce water and carbon dioxide.)
