Question

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)

Answer 1

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).
