Question

I have been trying this but I always have something wrong. Thanks for helping.

When aqueous solutions of ammonium carbonate and barium nitrate are combined, solid barium carbonate and a solution of ammonium nitrate are formed. The net ionic equation for this reaction is:

Answer 1

(NH4)₂CO₃(aq) + Ba(NO₃)₂(aq) ==> 2NH₄NO₃(aq) + BaCO₃(s) ... balanced equation (double replacement)

You must know the solubility of each species. Since we have a precipitate formed, the net ionic equation will contain only those ions involved in the precipitate.

Net ionic: Ba²⁺(aq) + CO₃^2-(aq) ==> BaCO₃(s)
