Natural gas has a chemical formula of C1.12H4. Using this formula, write a balanced equation, one for each fuel, for complete combustion in air. * Please note that Natural Gas' chem formula has a decimal as a subscript C (subscript: 1.12)H (subscript 4). I can not figure out how to work through this.
