A propane gas stove is used to heat a covered pot containing 455. g of water. The propane tank weighs 1.2522 kg before it is used, and 1.2497 kg after it is used. The temperature of the water

increases from 19.5 °C to 77.8 °C as a result of the heating. The specific heat capacity of water is 4.184 J/g °C.

a. balance the chemical equation for the reaction that happens, including state

symbols. Assume that excess oxygen is available.

b. Given the table of bond energies provided, calculate the theoretical molar heat of combustion

for the reaction.
