Write chemical equation for the following reactions. Indicate physical states and write net ionic equations. If no reaction indicate so.

Potassium carbonate + ammonium chloride

There is no reaction.

Molecular equation:

K₂CO₃ (aq) + 2NH₄Cl (aq) ⟶ 2KCl (aq) + (NH₄) ₂CO₃ (aq)

Ionic equation:

2K⁺ (aq) + CO₃²⁻ (aq) + 2NH₄⁺ (aq) + 2Cl⁻ (aq) ⟶ 2K⁺ (aq) + 2Cl⁻ (aq) + 2NH₄⁺ (aq) + CO₃²⁻ (aq)

Net ionic equation:

Cancel all ions that appear on both sides of the reaction arrow (underlined).

2K⁺ (aq) + CO₃²⁻ (aq) + 2NH₄⁺ (aq) + 2Cl⁻ (aq) ⟶ 2K⁺ (aq) + 2Cl⁻ (aq) + 2NH₄⁺ (aq) + CO₃²⁻ (aq)

All ions cancel. There is no net ionic equation.
