# Write the balanced equation of the complete combustion of butane C4H10?

Feb 28, 2018

$2 \text{C"_4"H"_10 + 13"O"_2 -> 8"CO"_2 + 10"H"_2"O}$

#### Explanation:

$\text{C"_4"H"_10 + "O"_2 -> "CO"_2 + "H"_2"O}$

Whenever it is said 'complete combustion', what must be remembered is just to write ${\text{CO}}_{2}$ instead of $\text{CO}$ (this is for 'incomplete combustion')

Now write coefficients:

$\text{C"_4"H"_10+ 13/2"O"_2 -> 4"CO"_2 + 5"H"_2"O}$

or we can multiply each side by $2$:

$2 \text{C"_4"H"_10 + 13"O"_2 -> 8"CO"_2 + 10"H"_2"O}$
