1)A metal strip X is dipped in blue coloured salt solution YSO4 

(a) What could be metal ‘X’ and ‘Y’ ?

Metal X is Zinc and Metal Y is copper.

(b) Name the metal salt YSO4

Metal salt is CuSO4

c)What type of chemical reaction takes place between X and YSO4 ? Write the balanced chemical equation.

Zn (s) +CuSO4(aq)-----> ZnSO4(aq) +Cu

Answer 2

YSO4 is Copper sulphate solution.

Y formed on strip is Copper (Cu)

X can be a variety of things like Iron (Fe)

Reaction:

CuSO4(aq) + Fe(s) → FeSO4(aq) + Cu(s)

I'm not sure about the other question, sorry :(
