Answer to Question #203295 in General Chemistry for jose

Question

The standard enthalpies of formation, at 25.00 °C, of methane (CH4(g)), water (H2O(I), 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 17.52 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.) Q

Answer 1

Amount of heat released=$674kJ$
