You measure the temperature of a calorimeter with a heat capacity of 3.4×104 J/ºC and you determine that the temperature of the calorimeter is 25.1ºC. Assume that the calorimeter loses no heat to the surrounding air and that the heat capacity of the reactants and solutions is negligible. After a chemical reaction occurs, you determine that the temperature of the calorimeter is 28.3ºC. Calculate the heat change of the calorimeter (Qcal) for this process and report it below with the correct number of significant figures
