The unbalanced chemical reaction is
<span>Na (s) + H2O (g) yields NaOH (aq) + H2 (g)

By inspection,
There is 1 mole of Na in both sides
There is 2 moles of H in the left and 3 moles in the right side.
</span>There is 1 mole of O in both sides
<span>
We balance the reaction by:

</span>2Na (s) + 2H2O (g) yields 2NaOH (aq) + H2 (g)

The answer is 2
