Answer:
[tex]H_{2}O[/tex] is the product.
Explanation:
In any chemical reaction, by convention, we write the reactants on the left hand side and the products of right hand side.
The given equation is combustion reaction of methane:
[tex]CH_{4}+2O_{2}--->CO_{2}+2H_{2}O[/tex]
Here methane is reacting with oxygen so methane and oxygen both are reactants.
The two are reacting to form carbon dioxide and water, so both carbon dioxide and water are products.
