# Mastering Chemistry Question!?

One possible use for the cooking fat left over after making french fries is to burn it as fuel.

Formula = C51H88O6

Density = 0.94 g/ml

Delta Hf= – 1310. kj/mol

Write a balanced equation of the combustion of cooking fat.

C(51)H(88)O(6) + O2 –> CO2 + H2O

‘A combustion reaction is when all substances in a compound are combined with oxygen, which then produces carbon dioxide and water.’

Balancing:

You have 51 Carbons so add 51 carbons to the other side.

C(51)H(88)O(6) + O2 –> 51CO2 + H2O

88 Hydrogens on one side multiple of 2 on the other so:

C(51)H(88)O(6) + O2 –> 51CO2 + 44H2O

finally balance the oxygens; 51*2 plus 44 on the right side and 6+2 on the left side, therefore:

C(51)H(88)O(6) + 70O2 –> 51CO2 + 44H2O
