A bomb calorimeter is filled with 9 atm of an unknown gaseous
hydrocarbon fuel and an excess of oxygen gas at a temperature of
20.5 °C. The bomb calorimeter has a volume of 4.1 L and a heat
capacity of 7.64 kJ/K. After the combustion reaction is complete
the final temperature of the calorimeter is found to be 333.3 °C.
Answer the following questions based on this information.
(a) What amount of heat in kJ was released from the combustion
reaction of the unknown fuel? Please give your answer to 2 decimal
places.
(b) What is the molar heat of combustion for the reaction in kJ/mol? Please give your answer to 2 decimal places.
(c) Given the table of data below, what is the identity of the unknown gas?
| Fuel | Chemical Formula | Molar Heat of Combustion |
|---|---|---|
| ethene | CH2CH2 | -1324.1 kJ/mol |
| ethane | CH3CH3 | -1560.6 kJ/mol |
| propane | CH3CH2CH3 | -2218.1 kJ/mol |
| propyne | CHCCH3 | -1849.6 kJ/mol |

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 0.466-g sample of 1,8-octanediol
(C8H18O2) in a bomb calorimeter containing 1200. g of water. The
temperature increases from 25.90 °C...

1.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 0.3807 g sample of
1,6-hexanediol (C6H14O2) is burned completely in a bomb
calorimeter. The calorimeter is surrounded by 1.139×103 g of water.
During the combustion the temperature increases from 25.30 to 27.59
°C. The heat capacity of water is 4.184 J g-1°C-1. The heat
