Write chemical equation for the following reactions. Indicate physical states and write net ionic equations. If no reaction indi
iren [92.7K]

There is no reaction.

<em>Molecular equation :</em>

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

<em>Ionic equation :</em>

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

<em>Net ionic equation :</em>

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

<u>2K⁺(aq)</u> + <u>CO₃²⁻(aq)</u> + <u>2NH₄⁺(aq</u>) +<u>2Cl⁻(aq)</u> ⟶ <u>2K⁺(aq)</u> + <u>2Cl⁻(aq</u>) + <u>2NH₄⁺(aq)</u> + <u>CO₃²⁻(aq)</u>

<em>All ions cancel</em>. There is no net ionic equation.
