When 1.640 g of titanium is combusted in a bomb calorimeter, the temperature of the calorimeter increases from 25.00 °c to 76.50 °c. in a separate experiment, the heat capacity of the calorimeter is measured to be 9.84 kj/k. the heat of reaction for the combustion of a mole of ti in this calorimeter is kj/mol?
