Write a balanced equation for the complete combustion of 2-methylpentane.?
- electron1Lv 72 years agoFavorite Answer
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.
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.

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