(d) Name the salt X(NO3)2
(e) What type of reaction takes place between metal X and salt solution YNO3?

(a) Copper is the red-brown strip of metal X.

(b) Silver nitrate is a colourless salt solution with the formula YNO3.

(c) Silver is the metal that forms a shining white deposit on the strip metal X when copper and silver nitrate solution react.

(d) Copper nitrate is the blue coloured salt formed X(NO3)2 as copper is present in the solution.

(e) The type of reaction taking place here is a displacement reaction.

Chemical equation involved is:

Cu(s) + 2AgNO3(aq) → Cu(NO3)2(aq) + 2Ag(s)
