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....
1. 2. 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...
1. 2. 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...
A 5.0L bomb calorimeter, with a heat capacity of 14.25 kJ/°C, is filled to a pressure of 5.0 atm with O2 gas at 32.9°C. A 6.55 g sample of aniline (C6H5NH2, molar mass = 93.13 g/mol) was then combusted in this calorimeter. Determine the value of the final temperature of the calorimeter. 4 C6H5NH2(l) + 35 O2(g) → 24 CO2(g) + 7 H2O(g) + 2 NO2(g) ΔH°rxn= -1.28 x 104kJ/mol
