A)2Na⁺(aq) + CO₃^2-(aq) → Na₂CO₃ (aq) B)2Na⁺ (aq) + 2Cl^- (aq) → 2NaCl (aq) C)Na⁺ (aq) + Cl^- (aq) → NaCl (aq) D)Ca⁺(aq) + CO₃^2- (aq) → CaCO₃ (s) E)Na₂CO₃ (aq) + Ca (aq) → 2NaCl (aq) + CaCO₃ (s)

Question

Quizplus · Accepted Answer

The balanced net ionic equation for precipitation of CaCO₃ is the equation that lists only the species involved in the reaction and removes any spectator ions that did not participate in the reaction. The given equations A, B, and C do not relate to the precipitation of CaCO₃. Therefore, the balanced net ionic equation for precipitation of CaCO₃ when aqueous solutions of Na₂CO₃ and CaCl₂ are mixed is: Ca⁺(aq) + CO₃²⁻(aq) → CaCO₃(s) Therefore, the answer is D.
