The enthalpy of combustion of benzoic acid (C6 H5 COOH) is commonly used as the standard for calibrating constant-volume bomb calorimeters; its value has been accurately determined to be −3226.7 kJ/mol. When 1.9862 g of benzoic acid are burned in a calorimeter, the temperature rises from 21.84°C to 25.67°C. What is the heat capacity of the bomb? (Assume that the quantity of water surrounding the bomb is exactly 2000 g.)
Liquid weighing 0.98 gram and containing 90% of carbon and 8% of hydrogen give the following result in the bomb calorimeter experiment amount of water taken in the calorimeter equal to 450 gram water equivalent of the calorimeter equal
to 450 gram rise in temperature of water equal to 1.8 degree centigrade if the latent heat of steam is 587 calorie per gram calculate the cross and net calorific value of the fuel
