Answer 2

Just remember the reactivity series!

here happens a displacement reaction.

so, a) the initial blue colour of copper sulphate is changed into light green colour of iron sulphate.

The initial silver colour of the iron nail changes into reddish brown due to the coating of copper on it.

b) yes! This is a chemical change!

c) Fe + CuSo4 -> FeSo4 + Cu

it means....

IRON + COPPER SULPHATE == > IRON SULPHATE + COPPER
