pre lab- heat of combustion (1-3D)
Experiment 10 HEAT OF COMBUSTION Pre-Lab 1. The Law of Conservation of Energy can be applied to combustion processes where fuel + oxygen products + energy The total chemical energy associated with the reactants must be the same as the total chemical energy of the products when the heat of combustion is included. a) Underline the graph which best represents the relationship between the stored chemical energy of the reactants and products in a...
