question 120

Multiple Choice

Give the complete ionic equation for the reaction (if any) that occurs when aqueous solutions of lithium sulfide and copper(II) nitrate are mixed.

• A) 2 Li⁺(aq) + S^2-(aq) + Cu²⁺(aq) + 2 NO₃^-(aq) → Cu²⁺(aq) + S^2-(aq) + 2 Li⁺(aq) + 2 NO₃^-(aq)
• B) 2 Li⁺(aq) + S^2-(aq) + Cu²⁺(aq) + 2 NO₃^-(aq) → CuS(s) + 2 LiNO₃(s)
• C) 2 Li⁺(aq) + S^2-(aq) + Cu²⁺(aq) + 2 NO₃^-(aq) → Cu²⁺(aq) + S^2-(aq) + 2 LiNO₃(s)
• D) 2 Li⁺(aq) + S^2-(aq) + Cu²⁺(aq) + 2 NO₃^-(aq) → CuS(s) + 2 Li⁺(aq) + 2 NO₃^-(aq)
• E) No reaction occurs.
