Mothballs are composed primarily of the hydrocarbon naphthalene (C10H8). When 1.025g of naphthalene is burned in a bomb calorimeter, the temperature rises from 24.25 degree C to 32.33 degree C.
Find Delta Erxn for the combustion of naphthalene. The heat capacity of the calorimeter, determined in separate experiment, is 5.11 kJ/ C
