Instructions:Select the correct answer.

Refer to the activity series chart and determine which of the following displacement reactions can occur.

2Ag (s) + Zn (NO3) 2 (aq) → 2AgNO3 (aq) + Zn (s)

2Cu (NO3) 2 (aq) + 2Ag (s) → 2AgNO3 (aq) + Cu (s)

CuSO4 (aq) + Fe (s) → FeSO4 (aq) + Cu (s)

3MgSO4 (aq) + 2Al (s) → Al2 (SO4) 3 (aq) + 3Mg (s)

Activity series of metals: K, Na, Mg, Al, Zn, Fe, Cu, Ag. Metals on the left are more reactive than metals on the right. For example Zn is more reactive than Fe and can displace him.

Reaction than can occur is: CuSO4 (aq) + Fe (s) → FeSO4 (aq) + Cu (s).
