Na + H2O===>NaOH + H2
There's one Na on the left and right, one O on the left and right but there's 2 H on the left and 3 H on the right so you need to make the H on left and right equal.
Na + 2H2O===>2NaOH + H2
Now the H on each side is equal because there's 4 H on the left and 4 H on the right but Now there's 1 Na on the left and 2 Na on the right so that's not balanced. You need to now balance Na.
2Na + 2H2O--->2NaOH + H2
Now there's 2 Na on the left and 2 Na on the right, 4 H on the left and 4 H on the right, 2 O on the left and 2 O on the right so it's balanced.
2Na + 2H2O--->2NaOH + H2
(I wasn't sure whether you wanted the equation balanced or not, but hope this helps)
