Photo 3: The reaction is strongly exothermic: The piece of sodium melts (melting point of sodium: 97. In this experiment the heat of fusion of ice will be determined by using the method of mixtures (Quantity of heat lost = Quantity of heat gained). The temperature change of the calorimeter is then related to the heat of combustion of ethanol (heat released in a reaction (combustion in this case) = heat gained by the calorimeter). For each metal, calculate the heat gained by the water using Q = mc(Tf-Ti). The enthalpy of combustion is the energy released by a combustion reaction between hydrocarbons, oxygen and a heat source.
