Answer 1

infer the reactivity series-

iron

copper

silver

gold

1. iron will displace copper to form green ferrous sulphate

2. no reaction (colour will be same i.e blue)

3. no reaction (colour will be same i.e blue)

Answer 2

The iron reacts with the copper sulfate and forms ferrous sulfate and copper. The ferrous sulfate formed is green in color and it leaves behind yellow colored copper.

The silver does not react with the copper sulfate and stays the same which is blue in color as silver is less reactive than copper.

The gold does not react with the copper sulfate and stays the same which is blue in color as gold is less reactive than copper.

So your answer is option C

Hope it helps.
