Write the net ionic equation for the precipitation of cobalt (ii) carbonate from aqueous solution

Missing question: Write the net ionic equation for the precipitation reaction that occurs when aqueous solutions of ammonium carbonate and cobalt (II) bromide are combined. Balanced chemical reaction:

(NH ₄) ₂CO₃ (aq) + CoBr₂ (aq) → CoCO₃ (s) + 2NH₄Br (aq).

Net ionic reaction:

2NH₄⁺ (aq) + CO²⁻ (aq) + Co²⁺ (aq) + 2Br⁻ (aq) → CoCO₃ + 2NH₄ (aq) + 2Br (aq).

or CO²⁻ (aq) + Co²⁺ (aq) → CoCO₃ (s).
