Question

The heat capacity of the bomb calorimeter was determined by burning 6.79 g methane (energy of combustion = -802 kJ/mole CH4) in the bomb. The temperature changed by 10.8°C.

a.) What is the heat capacity of the bomb? 

b.) A 12.6 g sample of acetylene, C2H2, produced a temperature increase of 16.9°C  in the same calorimeter. What is the energy of combustion of acetylene (in kJ/mol)

Expert Solution
