QUESTION:
The propane fuel (C3H8) used in gas barbeques burns according to the thermochemical equation:
If a pork roast must absorb 1.6 x 103 kJ to fully cook, and if only 10% 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?
ANSWER:Solution 63E: For the above reaction, 2217 kJ of heat is released when the propane fuel burns in air and 3 moles of CO 2(g) formed in this reaction. But only 10% of the
