II Review | Constants | Periodic Table The propane fuel (C2H8) used in gas barbeques burns according to the thermochemical equation: C3H8 (9) + 5O2(g) + 3CO2(g) + 4H2O(g) ArH = -2217 kJ mol-1 Part A If a pork roast must absorb 1.5 x 103 kJ to fully cook, and if only 12 % of the heat produced by the barbeque is actually absorbed by the roast, what mass of CO2 is emitted into the atmosphere during the grilling of the pork roast?
