Question

The table given below shows the reactions of metals with the solutions of metal salts.
on the basis of the above observation , arrange metals j,k and l in order of increasing reactivity series ​

Answer 1

Answer:

Metal J is the most reactive metal because in the displacement reaction it displaces metal K and L.

Metal K is the least reactive metal because in the displacement reaction it does not displace any metal.

Therefore the order is: -

Metal J

Metal L

Metal K

I think this is the answer!!

HOPE IT HELPS!!

Answer 2

Answer:

On the basis of the above observation, the order of increasing reactivity is:- K<L<J.

Explanation:

Metal K is the least reactive metal because in the displacement reaction it does not displaces any metal.

Metal L which is able to displace metal K as it is more reactive than metal K but it is not able to displace metal J as it is less reactive than J.

Metal J is the most reactive metal because in the displacement reaction it displaces metal K and L.
