A student mixed 50.0 mL of water containing 0.010 moles of HCI (weighing 50.0 g) with 60.0 mL of water containing 0.012 moles of NaOH (weighing 60.0 g) in a coffee cup calorimeter. Both solutions were initially at 25.00°C, but after reaction upon mixing the temperature rose to 26.20°C. The specific heat of the solution is the same as that of water, 4.18 J/g °C, and the calorimeter has a heat capacity of 35 J/°C. The reaction is shown below. (a) How much heat is produced in the reaction? (b) How much heat is produced if one mole of water is formed in this chemical reaction? HCl(aq) + NaOH(aq) → NaCl(aq) + H20(l)

A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy available from foods. Since the "bomb" itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter.
