##### 1 Answer

The balanced chemical equation for the combustion of propane is

#### Explanation:

The formula for propane is

So our equation is

where

**First balance the carbon.** There are 3 carbons on the left-hand side of the equation. To make 3 carbons on the right-hand side of the equation we must make

**Next balance the hydrogen.** There are 8 hydrogens on the left-hand side of the equation. In order to make 8 hydrogens on the right-hand side of the equation we must make

**Finally balance the oxygen.** There are now 10 oxygens on the right-hand side of the equation. In order to make 10 oxygens on the left-hand side of the equation we must make

This is our balanced chemical equation for the combustion of propane. Because this reaction produces heat, the change in enthalpy is negative (
