A. Explain how much heat is released when 25.0g of methane burns in excess oxygen to form gaseous CO2 and H2O?

B. Compute the temperature of the product mixture if the methane as well as air is both at an initial temperature of 0.0 degrees Celsius. Presume a stoichiometric ratio of methane to oxygen from the air, with air eing 21% O2 by volume c of CO2 = 57.2 J/mol k; c of H2O(g) = 36.0 J/mol k; c of N2 = 30.5 J/mol k.
