Use the Table above to answer the following questions about metals A, B, C and D
1. Which is the most reactive metal?
2. Arrange the metals A B C and D in the order of decreasing reactivity​

Answer 1

Answer:

ANSWER

(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 CuSO

4

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.

(iv) Metal D can be used to make containers to store the solutions because it is the least reactive metal of all.
