question 248

Multiple Choice

Identify the net ionic equation for the reaction (if any) that occurs when aqueous solutions of Na₂CO₃ and HCl are mixed.

• A) 2H⁺(aq) + CO₃^2-(aq) → H₂CO₃(s)
• B) 2Na⁺(aq) + CO₃^2-(aq) + 2H⁺(aq) + 2Cl^-(aq) → H₂CO₃(s) + 2NaCl(aq)
• C) 2H⁺(aq) + CO₃^2-(aq) → H₂O(l) + CO₂(g)
• D) 2Na⁺(aq) + CO₃^2-(aq) + 2H⁺(aq) + 2Cl^-(aq) → H₂CO₃(s) + 2Na⁺(aq) + 2Cl^-(aq)
• E) No reaction occurs.
