Question

18. Which of the following displacement reaction will (6) Occur? (ii) Not occur? Give reason
in each case
a. Cu(s) + MgSo. (aq) → Cuso, (aq) + Mg(s)
b. Pb(NO), (aq) + Zn(s) -- Zn(NO), +Pb(s)
c. ZnSO, (aq) + Cu(s) - Cuso, (aq) + Zn(s)​

Answer 1

Answer:

All are displacement reaction

Explanation:

because in (a)Cu displace Mg

in(b)Zn displace Pb and

in (c)Cu displace Zn

Answer 2

Answer:

a. Cu+MgSo....Cuso+Mg

c. ZnSO+Cu...CuSo+Zn

these two are displacement reaction

because in those two reaction element are displace and react with other element.
