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].

The “calories” listed on food packaging are actually kilocalories and a distinction is often made by capitalizing the C when referring to the calories in food. 1 food calorie= 1 Cal= 1kcal A serving of pancakes contains 230 Cal, how many Joules (J) would a serving contain? 1 cal = 4.184 J (here cal is not a food calorie)
