Answer

Explanation:

Step1: Identify common species

The common species between the two equations is $2H_2O(g)$.

Step2: Combine equations

Add the two given equations. The first equation is $CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)$ and the second is $2H_2O(g)\rightarrow 2H_2O(l)$. When we add them, the $2H_2O(g)$ on the right - hand side of the first equation and the $2H_2O(g)$ on the left - hand side of the second equation cancel out.

Answer:

$CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(l)$
