Answer 1

Answer:

not too much long question

Answer 2

Explanation:

Ans

. (i) B is the most reactive metal

(ii)If B is added to a solution of copper (II) sulphate, displacement reaction will take place. Blue colour of copper sulphate will fade and red –brown copper will settle down.

(iii) The decreasing order of reactivity is:

B> A> C >D
