Question

Which of the following pairs of reactants will react together to produce water (H2O) as one of the products? NaNO3 and H2O, Mg3(PO4)2 and Al2O3, Fe(Oh)3 and H2SO4,  or Li2O and Ba(OH)2

Water is always a product in acid-base neutralizations.  There is one acid-base neutralization on you list -- you can recognize them by the prefix H- and the suffix -OH.
So they are Fe(OH)3 and H2SO4.
