A calorimeter containing 769.0 g of water at an initial temperature of 25.00 °C was used to measure the heat involved in a reaction. When the reaction was finished, the temperature of the water increased to 33.90 °C. Is the reaction endothermic or exothermic and how much heat energy involved in the reaction? (swater=4.184 J/goC)  The reaction is [1]. The amount of heat exchanged is [2].
