Your barbecue grill uses propane (C3Hg) to cook your food while butane (C4H10) is used in chemistry laboratories to perform experiments. Write an equation for hydrocarbon combustion for each of the gases and then balance.
Are these reactions endothermic or exothermic? How do you know?
Assume that the gases burn clean and completely, calculate the energy released by each in kJ/mole.
Calculate the energy released in kJ/g. Which gas is more efficient?
