The equation is [balanced/unbalanced], because the number of hydrogen atoms and [oxygen/sodium] atoms is [equal/not equal] in the reactants and in the products.
unbalanced. _______ and not equal. in not sure about the 2nd choice from the info im looking at. the balanced version is 2NaOH + H2SO4 = Na2SO4 + 2H2O (i hope this helps a little)
