Step 1

Combustion reactions are those chemical reactions in which hydrocarbons are burnt in the presence of air or oxygen in order to produce carbon dioxide and water.

Step 2

The heat capacity of the calorimeter (Ccal) is given to be 4440 J/oC.

The change in the temperature of the system is given to be 4.00oC.

The heat of the calorimeter can be calculated using the following equation as follows:

Step 3

The heat which has been released by the system is the he...
