Answer 1

Here are your answers mate:

Answers :-

(i) B is the most reactive metal as it has displaced the most reactive metal amongst the solutions i.e Fe of FeSO 4

(ii) If B is added to CuSO4

solution than it will displace Cu because Fe is more reactive than Cu so the metal which can displace Fe can also displace Cu.

(iii) D < C < A < B.
