At constant volume, the heat of combustion of a particular compound, compound A, is −3294.0 kJ/mol. When 1.127 g of compound A (molar mass = 109.35 g/mol) is burned in a bomb calorimeter, the temperature of the calorimeter (including its contents) rose by 7.283 °C. What is the heat capacity (calorimeter constant) of the calorimeter? Suppose a 3.157- g sample of a second compound, compound B, is combusted in the same calorimeter, and the temperature rises from 23.23 °C to...

A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods In an experiment, a 0.3568 g sample of bianthracene (C28H18) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.030x10 g of water. During the combustion the temperature increases from 25.45 to 28.29 °C. The heat capacity of water is 4.184 J gC The heat capacity of the...

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. In the laboratory a student burns a 0.425-g sample of diphenylacetylene (C14H10) in a bomb calorimeter containing 1170. g of water. The temperature increases from...
