Question

What are the products of complete combustion of octane?

Answer 1

Carbon Dioxide (`CO_2`) & Water (`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` + `O_2` = `CO_2`

`4H` + `O_2` = `2H_2O`

For Octane this would be;

2`C_8H_18` + 25`O_2` = 16`CO_2` + 18`H_2O`
