Silver shine
copper is placed above the silver in the ractivity series which indicates that copper is more reactive than silver . when a copper coin is kept immersed in a solution of siler nitrate ,silver from its solution will deposit on copper coin . copper slowly displaces silver from the silver nitrate solution and the colour of solution changes from colourless to blue due to the formation of copper nitrate . the copper coin will disappear and silver will percipate out .

zinc granules will have their colour changed to brownish black in colour.
Iron is more reactive than copper in the reactivity series. Hence metallic iron will displace copper cations from the solution. The solution will change colour from blue to brown. Metallic copper may be seen forming/observed on the sides of the reaction vessel/test tude.

Cu(s) + AgNO3(aq) => Ag(s) + CuNO3(aq)
zinc granules will have their colour changed to brownish black in colour.
Cu + 2AgNO3 ---> Cu(NO3)2 + 2Ag Silver breaks its bond with nitrate and Metallic Copper bonds to the nitrate with Silver changing into its metallic state or 0 charge state.
Why does the colour of copper sulphate solution change when an iron nail is dipped in it? When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour. Therefore, the blue colour of copper sulphate solution fades and green colour appears.

The silver piece of zinc dissolves forming zinc ions. Copper(ii) reduce into copper(i) ions. The blue color of the solution decreases.
Iron is more reactive than copper in the reactivity series. Hence metallic iron will displace copper cations from the solution. The solution will change colour from blue to brown. Metallic copper may be seen forming/observed on the sides of the reaction vessel/test tude.
the solution turns green and the nails develop a brown deposit which is copper. the iron displaces the copper in the copper sulphate solution. This is because iron is more reactive than copper.
