How to find the energy and heat released?

Question

1.00mol of propene sample is placed in an oxygen filled calorimeter and burned. The starting temperature of the calorimeter is 25.00°C and its total heat capacity is 97.1kJ/°C. The temperature of the calorimeter increased to 27.282°C. Find a), b) and c)?
a) Chemical equation that balances the reaction in the calorimeter.
b) How many J of energy were emitted in this reaction?
c) What is the heat released from the reaction of oxygen and propene when burning 1 mol of C3H8

Answer 1

(a) 2C3H6 + 9O2 ==> 6CO2 + 6H2O

(b) q = 97.1 kJ/deg x 27.28 deg = 2649 kJ =2,649,000 J

(c) 2,649,000 J/2 moles = 1,324,444 J from 1 mole
