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...

7. A 3.25 g sample of methanol, CH3OH, is combusted in a bomb calorimeter. The temperature of the calorimeter increases by 10.6°C. If the heat capacity of the bomb is 855 J/C° and it contains 1.000 kg of water, what is the heat evolved per mole of ethanol combusted? (The specific heat capacity of water is 4.184 J/g:K) (15 pts.)
A bomb calorimeter has a heat capacity of 675 J/°C and contains 925 g of water
A bomb calorimeter has a heat capacity of 675 J/°C and contains 925 g of water. If the combustion of 0.500 mole of a hydrocarbon increases the temperature of the calorimeter from 24.26°C to 53.88°C, determine the enthalpy change per mole of hydrocarbon. The specific heat of water = 4.184 J g-1 °C-1.Just the answerWhat is the enthalpy change when 175 g of C3H8 are burned in excess O2? C3H8(g) + 5 O2(g) ® 3 CO2(g) + 4 H2O(l) DH°...
