Net ionic equations

Question

Write a net ionic equation for the reaction that occurs when excess nitric acid(aq) and ammonium carbonate(aq) are combined.

(Be sure to specify states such as (aq) or (s). If a box is not needed leave it blank. If no reaction occurs leave all boxes blank and click on "submit". Use H⁺ for hydronium ion.)

Answer 1

2HNO₃(aq) + (NH₄)₂CO₃(aq) ==> 2NH₄NO₃(aq) + CO₂(g) + H₂O(l) ... molecular equation

2H⁺(aq) + 2NO₃^-(aq) + 2NH₄⁺(aq) + CO₃^2-(aq) ==> 2NH₄⁺(aq) + 2NO₃^-(aq) + CO₂(g) + H₂O(l).. ionic

2H⁺(aq) + CO₃^2-(aq) ==> CO₂(g) + H₂O(l) ... net ionic
