Plz help......

Answer 1

Answer:

Zinc is more reactive than iron, hence when added' to iron (II) sulphate, it can displace iron metaliand the colour of solution fades from green to colourless due to formation of zinc sulphate. The greyish black iron metal gets deposited. 8.

Answer 2

Explanation:

To observe the action of Zn, Fe, Cu and Al metals on the following salt solutions:

ZnSO4 (aq)

FeSO4 (aq)

CuSO4 (aq)

Al2(SO4)3 (aq)

Arrange Zn, Fe, Cu and Al metals in the decreasing order of reactivity based on the above results.

The Theory

Metals are elements and are good conductors of heat and electricity. Most metals are electropositive in nature and the metal atoms lose electrons in chemical reactions to form cations. The more reactive a metal, the greater tendency it has to form a positive ion in a chemical reaction.

For example:
