1. wa. Molecular form.

2. wa. Molecular form.

3. sa. Ionic form.

Explanation:

1. hydrocyanic acid

HCN is a weak acid. That means that in the following equilibrium, the molecular form (HCN (aq)) is favored, and that's how it should be written in solution.

HCN (aq) ⇄ H⁺ (aq) + CN⁻ (aq)

2. hypochlorous acid

HClO is a weak acid. That means that in the following equilibrium, the molecular form (HClO (aq)) is favored, and that's how it should be written in solution.

HClO (aq) ⇄ H⁺ (aq) + ClO⁻ (aq)

3. hydrochloric acid

HCl is a strong acid. That means that it completely dissociates and it should be written in the ionic form (H⁺ (aq) + Cl⁻ (aq)) when it is in solution.

HCl (aq) → H⁺ (aq) + Cl⁻ (aq)
