What are the products of complete combustion of octane?

1 Answer

Nov 22, 2017

Carbon Dioxide ( $C O_{2}$ $CO_2$ ) & Water ( $H_{2} O$ $H_2O$ )

Explanation:

Octane is made up of simply Carbon & Hydrogen.

In complete combustion, all the carbon and hydrogen atoms present react with oxygen ('combust') and thus the following occurs;

$C$ $C$ + $O_{2}$ $O_2$ = $C O_{2}$ $CO_2$

$4 H$ $4H$ + $O_{2}$ $O_2$ = $2 H_{2} O$ $2H_2O$

For Octane this would be;

2 $C_{8} H_{18}$ $C_8H_18$ + 25 $O_{2}$ $O_2$ = 16 $C O_{2}$ $CO_2$ + 18 $H_{2} O$ $H_2O$
