Chemistry

The enthalpy change for a chemical reaction is the sum of theenergy consumed in breaking bonds and the energy released duringbond formation. One way to determine the overall energy change fora chemical reaction is to apply Hessâ€™s law to add together a groupof reactions which can be arranged such that the chemicalequations, when combined, give the overall equation we are tryingto characterize.
part 1
Write a balanced chemical equation for the combustion of gaseouspropane in gaseous oxygen to produce gaseous carbon dioxide andliquid water.
part 2
Combine the following equations to determine the enthalpy changefor the combustion of 1 mole of propane. Assume that solid carbonis graphite.
Part 3
The average propane cylinder for a residential grill holdsapproximately 18 kg of propane. How much energy (in kJ) is releasedby the combustion of 18.50 kilograms of propane in sufficientoxygen?
