# What sort of reaction occurs when methane and oxygen gas react?

May 4, 2017

Well, this represents a combustion reaction........

#### Explanation:

And all chemical reactions balance (i), mass, and (ii) charge:

$C {H}_{4} \left(g\right) + 2 {O}_{2} \left(g\right) \rightarrow C {O}_{2} \left(g\right) + 2 {H}_{2} O \left(l\right)$

Because strong $C = O$ and $O - H$ bonds have been formed in the reaction, the reaction is exothermic, i.e. it releases energy:

$C {H}_{4} \left(g\right) + 2 {O}_{2} \left(g\right) \rightarrow C {O}_{2} \left(g\right) + 2 {H}_{2} O \left(l\right) + \Delta$

The energy produced is certainly quantifiable. At the moment, such combustion reactions will be heating our homes, and cooking our breakfast.
