Expert Solution
Step 1

If any hydrocarbon is burned completely in presence of oxygen then the type of reaction is called combustion reaction.

The products for this reaction are carbon dioxide and water. 

The no. of moles of carbon and hydrogen can be calculated and then further calculations are performed.
