Multiple Choice

What is the net ionic equation for the reaction that occurs when aqueous solutions of Pb(NO₃) 2 and NH₄Cl are mixed?

• A)Pb(NO₃)₂(aq)+ 2NH₄Cl(aq)→ 2NH₄NO₃(aq)+ PbCl₂(s)
• B)Pb²⁺(aq)+ 2Cl^-(aq)→ PbCl₂(s)
• C)Pb²⁺(aq)+ 2NO₃^-(aq)+ 2NH₄⁺(aq)+ 2Cl^-(aq)→ 2NH₄⁺(aq)+ 2NO₃^-(aq)+ PbCl₂(s)
• D)NH₄⁺(aq)+ NO₃^-(aq)→ NH₄NO₃(s)
• E)NH₄⁺(aq)+ NO₃^-(aq)→ 2NO(g)+ 2H₂O(l)
