Question

(viii) When a metal A is dipped in a solution of B, it replaces B from it. When a metal
C is dipped in a solution of A, it replaces A from its salt solution. Arrange the
metal in order of their decreasing reactivity.
​

Answer 1

Answer:

A<B<C

Explanation:

Answer 2

Answer:

(a) A is more reactive than B

More reactive metal (A) can displace a less reactive metal (B) from its salt solutions. More reactive metals are placed above comparatively less reactive metals in the reactivity series and can displace metals below them in the reactivity series
