The combustion of acetylene C2H2, takes place according to the equation:
2C2H2 + 5O2 ---> 4CO2 + 2H2O; delta H is -5198 kJ
In an experiment, 0.338 g C2H2 is combusted in a bomb calorimeter. If the heat capacity of the calorimeter is 729 J/K and it contains 1/150 kg of water, what is the temperature increase of the bomb calorimeter? The spedicif heat capacity of water is 4/184 J/g.K

Thermometer Ignition wires heat sample Stirrer A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of 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.
