# Write a balanced equation for the complete combustion of 2-methylpentane.?

Pentane means there are five carbon atoms in a straight line. 2-methyl means a methyl group is attached to the second carbon. If you go to the website below, you will see the structural formula of the compound. Its formula is C6H14. For complete combustion to occur, it must react with oxygen. The products are carbon dioxide and water.

https://en.wikipedia.org/wiki/2-Methylpentane

C6H14 + O2 → CO2 + H2O

To balance the carbon atoms, make six carbon dioxides. To balance the hydrogen atoms, make seven waters.

C6H14 + O2 → 6 CO2 + 7 H2O

The right side of this equation has nineteen oxygen atoms. To balance the oxygen atoms, make 8.5 O2.

C6H14 + 8.5 O2 → 6 CO2 + 7 H2O

To have whole number coefficients, double each of them.

2 C6H14 + 19 O2 → 12 CO2 + 14 H2O

I hope this is helpful for you.

Complete combustion....

2C6H14(g) + 19O2(g) --> 12CO2(g) + 14H2O(g)
