Question

ans plzzzzzzzzz..........​

Answer 1

i) Zn + Pb2+ -----> Zn2+ + Pb

Half oxidation reaction :-

Zn -----> Zn2+ + 2e-

Half reduction reaction :-

Pb2+ ----------> Pb - 2e-

Pb2+ + 2e- ----------> Pb

ii) Zn + Cu2+ -----> Zn2+ + Cu

Half oxidation reaction :-

Zn - 2e-  ------> Zn2+

Zn -----> Zn2+ + 2e-

Half reduction reaction :-

Cu2+ ----------> Cu - 2e-

Cu2+ + 2e- ----------> Cu

iii) Cl2 + 2Br- ---------> Br2 + 2Cl-

Half oxidation reaction :-

2Br-  2e-  -----> Br2

2Br-  ------> Br2 + 2e-

Half reduction reaction :-

Cl2 ----------> 2Cl- - 2e-

Cl2 + 2e- ----------> 2Cl-

Hope this helps! :)
