change is Y. Identify X and Y. Name and define the type of reaction.

Answer 1

Answer:

The product X is ferrous sulphate.....

And the colour is green.....

The reaction is Displacement reaction.......

The reaction in which a higher reactive metal displaces a less reactive metal from its compound is called displacement reaction.....

Answer 2

$\mathfrak{\huge{\orange{\underline{\underline{Answer :}}}}}$

X - Iron Sulphate

Y - Green

Type - Displacement Reaction

Iron being more reactive than copper will displace copper from its salt and form a subsequent salt of ferrous sulphate. During the reaction, the colour of copper sulphate [blue] will change to greenish-blue {ferrous sulphate}.
