Question 1

Identify the spectator ions in the following molecular equation:

KBr(aq) + AgNO3(aq) → AgBr(s) + KNO3(aq)

◦ Ag+ and NO3-
◦ Ag+ and Br-
◦ K+ and NO3-
◦ K+ and Br-
◦ There are no spectator ions in this reaction.

Question 2

Identify the complete ionic equation for the reaction (if any) that occurs when aqueous solutions of lithium sulfide and copper(II) nitrate are mixed.
◦ 2Li+(aq) + S2-(aq) + Cu2+(aq) + 2NO3-(aq) → CuS(s) + 2Li+(aq) + 2NO3-(aq)
◦ Li+(aq) + SO42-(aq) + Cu+(aq) + NO3-(aq) → CuS(s) + Li+(aq) + NO3-(aq)
◦ 2Li+(aq) + S2-(aq) + Cu2+(aq) + 2NO3-(aq) → Cu2+(aq) + S2-(aq) + 2LiNO3(s)
◦ Li+(aq) + S-(aq) + Cu+(aq) + NO3-(aq) → CuS(s) + LiNO3(aq)
◦ No reaction occurs.
