To write the neutralization reaction for the given acids and bases, we need to identify the reactants and products involved.

The acid given is HNO3(aq), which is nitric acid, and the base is Ba(OH)2(aq), which is barium hydroxide.

The general equation for a neutralization reaction between an acid and a base is:

acid + base → salt + water

Accordingly, the reaction between HNO3 and Ba(OH)2 can be written as:

HNO3(aq) + Ba(OH)2(aq) → Ba(NO3)2(aq) + H2O(l)

The balanced chemical equation for this reaction is:

2 HNO3(aq) + Ba(OH)2(aq) → Ba(NO3)2(aq) + 2 H2O(l)

In this equation, the salts formed are Ba(NO3)2, which is barium nitrate, and water (H2O).

Note: (aq) represents an aqueous solution, and (l) represents a liquid phase.
