Question 5 (1 point) In order to calibrate a constant volume bomb calorimeter, the combustion of (7.8100x10A-1) g of benzoic acid, C H5COOH, was observed to cause the temperature in the calorimeter to rise from 25.000 to (3.083x10^1) °C. The energy of combustion of benzoic acid, AU, is -3226.7 kJ mol1, What is total heat capacity (C) of the calorimeter (including all its contents) in kJ °C1? Pay attention to significant figures, keeping in mind that a temperature difference is...

5) Naphthalene combustion can be used to calibrate the heat capacity of a bomb calorimeter. When 0.8210 g of naphthalene was burned in a calorimeter containing 1,000. g of water, a temperature rise of 4.21°C was observed. The heat capacity of the bomb calorimeter excluding the water is 3.64 kJ/°C. What is the heat of combustion of naphthalene in kJ/g? (5 pts)

A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy sontent of foods. lastered 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 0.500-g sample of benzoic acid (C H02) in a bomb calorimeter containing 1030. g of water. The temperature increases...
