In this lab, you are going to calculate the heat of combustion of a candle two different ways and compare the results. You will first calculate the heat of combustion using the heat of formation of the products and reactants. Then you will actually burn a candle and determine the heat of reaction using calorimetry. To compare the results of the two methods, you will calculate the percent difference between the two values. Your hypothesis should state how closely you think the two values will compare.
