Checking the Balanced Equation

The number of a particular type of atom within a chemical formula embedded in an equation is obtained by multiplying the subscript for the atom by the coefficient for the chemical formula.
If there is no coefficient or subscript, a 1 is implied.
The balanced equation for the combustion of natural gas is as follows:
