Question

D. Complete the following reactions
1. Cuso4, (aq) + Zn(s)
2. Cuso4, (aq) + Fe(s)
3. Znso4, (aq) + Cu(s)
4. Feso4, (aq) + Cu(s)
5. Znso4, (aq) + Fe(s)​

Answer 1

Answer:

1. Cuso4 + Zn = ZnSO4 + Cu

2. Cuso4 + Fe = FeSO4 + Cu

3. ZnSO4+ Cu = ZnSO4

4. FeSO4+ Cu = FeSO4

5. ZnSO4+ Fe = ZnSO4

Questions 1 and 2 undergo displacement reaction.

In Questions 3, 4 and 5 no reaction happens since Zinc and iron are more reactive than copper. Thus Zinc can displace copper and iron

Iron can displace copper but not zinc

Copper cannot displace iron or zinc.

Answer 2

Answe1.znso4(aq) + cu(s)

2.feso4(aq) +cu(s)

3.cuso4(aq) +zn(s)

4.cuso4(aq) +fe(s)

5.feso4(aq)+zn(s)

Explanation:all are displacement reactions and in every case the metal present in solid form is more reactive than metal present in compound.
