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. In the laboratory a student burns a 0.330-g sample of diphenylacetylene (C14H10) in a bomb calorimeter containing 1170. g water. The temperature increases from 24.10 °C to 26.40 °C. The specific heat capacity of water is 4.184 J g1 °C•!. The combustion enthalpy is -7251 kJ/mol diphenylacetylene. C14H10(s) + 33/2 O2(g) →14 CO2(g) + 5 H2O(1) A,H° = -7251 kJ/mol Calculate the heat capacity of the calorimeter. heat capacity of calorimeter = J/°C

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. In the laboratory a student burns a 0.459-g sample of decanoic acid (C10H2002) in a bomb calorimeter containing 1120. g water. The temperature increases from 24.70 °C to 27.60 °C. The specific heat capacity of water is 4.184 J g-1 °C*!. The combustion enthalpy is -6080. kJ/mol decanoic acid. C10H2002(s) + 14 O2(g) →10 CO2(g) + 10 H20(1) 4,H° = -6080. kJ/mol Calculate the heat capacity of the calorimeter. heat capacity of calorimeter = Cי/נ
