Naoh (aq) + h2so4 (aq) > h2o + naso4 (aq)

Explanation:

Let's correct and balance the given equation:

is sodium hydroxide, charge of sodium is +1, charge of hydroxide is -1, so it's fine; is sulfuric acid, charge of hydrogen cation is +1, charge of sulfate is -2, sulfate is balanced by the two protons; is firstly a molecule, it's water, in its liquid state, the oxidation state of +1 for the two hydrogens is balanced by the oxidation state of -2 for oxygen;sodium sulfate should be , since sulfate has a charge of -2, this would require two sodium cations to balance it.

The equation becomes:

We require 2 NaOH in order to balance the two sodium cations on the right, this would yield a total of 4 hyrogens on the left, so we also need two water molecules to balance it fully:
