Answer
The balanced chemical equation for this reaction is:
$CO(g) + 3 H_2(g) \rightarrow CH_4(g) + H_2O(l)$
Work Step by Step
Gaseous carbon monoxide $(CO)$ and hydrogen gas $(H_2)$ are the reactants.
Gaseous methane $(CH_4)$ and liquid water $(H_2O)$ are the products.
The balanced chemical equation for this reaction is:
$CO(g) + 3 H_2(g) \rightarrow CH_4(g) + H_2O(l)$
