A calorimeter containing 785.0 g of water at an initial temperature of 25.0 °C was used to measure the heat involved in a reaction. When the reaction was finished, the temperature of the water increased to 42.5 °C. Is the reaction endothermic or exothermic and how much heat energy is involved in the reaction? (swater=4.184 J/goC) The reaction is . The amount of heat exchanged is .
