Which overall chemical equation is obtained by combining these intermediate equations

CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l)

Explanation:

To obtain the overall reaction, we add the two equations and omit the intermediates.The intermediate is the reaction species that appeared in one step and consumed in the following steps.The intermediate here is H₂O(g) that appears in the first step and has been consumed in the second step.

So, the overall reaction is: CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l)

Variables,control,conclusion and finally scientific theory

Sorry i dont understand the question can you rephase it?
