What is an exothermic reaction?
An exothermic reaction produces excess heat as the reactants turn to products. This means that the temperature of the glass flask would rise as the reaction occurs. The net change in energy during a reaction can be calculated by finding the sum of the formation energies of each compound. (would then give an example)
