Benzoic acid, C7H6O2, occurs naturally in many berries. A 1.50-g sample of benzoic acid is combusted in a bomb calorimeter. The temperature of the calorimeter increases from 22.50 0C to 31.69 0C. The calorimeter contains 775 g water and has a heat capacity of 893 J/0C. Based on this information, how much energy (in kJ) is released when you metabolize 1.50 g of benzoic acid? The specific heat capacity of water is 4.184 J/(g⋅0C).

Bomb calorimetry is a technique used to determine the enthalpy of combustion, usually in O2, of a chemical species. A known amount of compound is placed inside a fixed volume container that is, in turn, filled with oxygen at a high enough pressure to ensure complete combustion. The fixed-volume container (the 'bomb') is then inserted into a bucket containing a precisely known volume of water. The oxygen and compound are ignited, and the temperature change in the water is recorded....
