Write a net ionic equation for the reaction that occurs when excess aqueous nitric acid is combined with solid chromium(II) carbonate.

Answer 1

2HNO₃(aq) + CrCO₃(s) ==> Cr(NO₃)₂(aq) + CO₂(g) + H₂O(l) ... complete molecular equation

2H⁺(aq) + 2NO₃^-(aq) + CrCO₃(s) ==> Cr²⁺(aq) + 2NO₃^-(aq) + CO₂(g) + H₂O(l) ... ionic equation

2H⁺(aq) + CrCO₃(s) ==> Cr²⁺(aq) + CO₂(g) + H₂O(l) ... net ionic equation
