# Methane bums in oxygen to yield carbon dioxide and water. The chemical formula for this reaction is CH_4 + 2O_2 -> CO_2 + 2H_2O. What is the product, or what are the products, of this reaction?

Clearly, the products of the reaction are $\text{carbon dioxide}$ and $\text{water........}$, as with any complete hydrocarbon combustion,
$C {H}_{4} \left(g\right) + 2 {O}_{2} \left(g\right) \rightarrow C {O}_{2} \left(g\right) + 2 {H}_{2} O \left(l\right) + \Delta$
