With a good explanation please.
An amount of 3.355 g ethanol C2H5OH(1) is burned completely in a calorimeter at 298.15 K. The heat produced is 99.472 kJ. It can be assumed that the measurement takes place under constant pressure of 1 bar. C2H5OH(1) + 302(g) + 2CO2(g) + 3H2O(1) 3a.

Heat Capacity and Calorimetry
A sample of ethanol, C2H5OH, weighing 2.84 g was burned in an
excess of oxygen in a bomb calorimeter. The temperature of the
calorimeter rose from 25C to 33.73C. If the heat capacity of the
calorimeter and contents is 9.63kJ/C, what is the value of q for
burning 1.00 lol of ethanol at constant volume and 25.00C.
Is q equal to U or H?
