Question

An element X displaces iron from the aqueous solution of iron sulphate .List your observations if the element X is treated with the aqueous solutions of copper sulphate, zinc sulphate and silver nitrate . based on the observations arrange X,Zn,Cu and Ag in increasing order of their reactivities.​

Answer 1

Answer:

Hey mate! Gm! Here is your answer :)

Explanation:

The element X is Magnesium, as magnesiumis more reactive from iron & hence, it displaces iron from the aqueous solution of iron

sulphate.

Observations:

Magnesium 

with copper sulphate: Mg + CuSO4--> MgSO4+Cu

Magnesium with zinc sulphate: Mg+ ZnSO4--> MgSO4+Zn

Magnesium with silver nitrate: Mg + 2AgNO3-->Mg(NO3)2+2Ag.

Increasing order of their reactivities:

Ag<Cu<Fe<Zn<Mg

Answer 2

Answer:

magnesium is the metal x displace iron from the aqueous solution
