Verified step by step guidance

Identify the reactants: zinc (Zn) is a metal, and nitric acid (HNO3) is an acid containing the nitrate ion (NO3⁻).

Recall that when a metal reacts with an acid, it typically forms a salt and hydrogen gas. The salt is composed of the metal cation and the anion from the acid.

Determine the charge on the zinc ion: zinc commonly forms a +2 charge, so the zinc ion is Zn²⁺.

Identify the anion from nitric acid: the nitrate ion, NO3⁻, has a -1 charge.

Combine the ions to form a neutral salt: since Zn²⁺ has a +2 charge and NO3⁻ has a -1 charge, two nitrate ions are needed to balance one zinc ion, resulting in the formula Zn(NO3)2.
