Solution: An LP gas tank in a home barbeque contains 13.2 kg propane (C3H8). Calculate the heat (kJ) associated with the complete combustion of all the propane in the tank.            C3H8   +   5 O2   →   3 CO

Problem

An LP gas tank in a home barbeque contains 13.2 kg propane (C3H8). Calculate the heat (kJ) associated with the complete combustion of all the propane in the tank.

            C3H8   +   5 O2   →   3 CO2   +   4 H2O                        ∆Hrxn = -2044 kJ
