A bomb calorimetric experiment was run to determine the enthalpy of combustion of ethanol. The reaction is C2H5OH(l) + 3 O2(g) → 2 CO2(g) + 3 H2O(l) The bomb had a heat capacity of 500 J/K, and the calorimeter contained 610 g of water. Burning 4.50 g of ethanol, C2H5OH(L) resulted in a rise in temperature from 16.5 °C to 20.9 °C. Calculate the enthalpy of combustion of ethanol, in kJ/mol.

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 0.3320 g sample of naphthalene (C10Hg) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.092x103 g of water. During the combustion the temperature increases from 22.54 to 25.04 °C. The heat capacity of water is 4.184 Jg=1°C-1 The heat capacity of the calorimeter was determined...

A 2.50 g sample of ethanol, C2H5OH, was combusted in the presence of excess oxygen in a bomb calorimeter containing 2.00 kg of water. The temperature of the water increased from 22.500oC to 27.845oC. The heat capacity of the calorimeter is 2520 J/oC and the specific heat capacity of water is 4.184 J/goC. Calculate the molar enthalpy of the combustion reaction in kJ/mol

Bomb calorimetry is a technique used to determine the enthalpy of combustion, usually in O2, of a chemical species. A known amount of compound is placed inside a fixed volume container that is, in turn, filled with oxygen at a high enough pressure to ensure complete combustion. The fixed-volume container (the 'bomb') is then inserted into a bucket containing a precisely known volume of water. The oxygen and compound are ignited, and the temperature change in the water is recorded....

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...
