Enter your answer in the provided box. The enthalpy of combustion of benzoic acid (CH COOH) is commonly used as the standard for calibrating constant-volume bomb calorimeters; its value has been accurately determined to be -3226.7 kJ/mol. When 3.0653 g of benzoic acid are burned in a calorimeter, the temperature rises from 21.84°C to 24.67°C. What is the heat capacity of the bomb? (Assume that the quantity of water surrounding the bomb is exactly 2250 g.) kJ/°C

Benzoic acid is used to determine the heat capacity of bomb calorimeters because it can be obtained in pure form and its enthalpy of combustion is known very accurately (-26.43 KJ/g). Determine the heat capacity of a calorimeter that had a temperature increase of 7.250°C when 2.500 g of benzoic acid was used. Select one: a.-9.114 kJ/°C b.-18.23 kJ°C c. 18.23 kJ°C d. 4.557 kJ/°C e. 9.114 kJ°C

A student runs two experiments with a constant-volume "bomb" calorimeter containing 1200. g of water (see sketch at right). thermometer stirrer water First, a 8.000 g tablet of benzoic acid (C H CO,H is put into the "bomb" and burned completely in an excess of oxygen. (Benzoic acid is known to have a heat of combustion of 26.454 kJ/g.) The temperature of the water is observed to rise from 12.00 °C to 48.74 °C over a time of 11.3 minutes....
