Based on the observations recorded in the table,
answer the following:
(1) Which is the most reactive metal?
(2) Which is the least reactive metal?
(3) What would be observed if metal D were added to a
solution of copper (II) sulphate?
(4) What would be observed if metal E were added to a
solution of iron (II) sulphate?
(5) Arrange the metals A, B, C, D and E in decreasing​

Answer 1

Answer:

ANSWER IS GIVEN. MARK ME AS THE BRAINIEST!

Explanation:

(a) E is most reactive. Because it reacts with most substances.

(b) E>B>A>C>D : The more it reacts the more reactive it is.  

(d) Container of metal D can be used for this purpose as it does not react with any of them.

(e) Aluminium and magnesium sulphates can be used to store in any container because the react with none.
