In the burning of natural gas, methane (CH4) and oxygen (O2) are the reactants in the chemical reaction. are the substances formed by a chemical reaction. In the burning of natural gas, carbon dioxide (CO2) and water (H2O) are the products formed by the reaction.   2. H2+O2 ----> H2O Here H2 & O2 are called Reactants and H2O is called Product.
