When .0430 mole of titanium is combusted in a bomb calorimeter, the temperature of the calorimeter increases from 30.00degress Celsius to 91.60 degrees Celsius. In a separate experiment, the heat capacity of the calorimeter is measured to be 9.84kJ/K. The heat of reaction for the combustion of a mole of Ti in this calorimeter is ______?
The answer is supposed to be -1.52*10^4
Can someone please explain the process of how to get this answer?
