Question

Q4 In a solution of copper sulphate, a strip of metal M was inserted. Alter
sometime, the colour of copper sulphate solution faded away. Which
metal is more reactive and which one is less? Give equation Also
mention the type of reaction.
Q5. Name one metal which can displace zinc from its salt solution and one
metal which cannot displace zinc from its salt solution
​

Answer 1

cuso4 + M -- Mso4 + cu this is the eq. of the rxn.

metal M is more reactive then copper

Q.5 --the metal which displaces zinc is Mg and which cannot displace zinc is Au.

hope it helps uh ..

Answer 2

In a solution of Copper sulpate, a strip of metal was inserted after that sometime the colour of Copper Sulphate solution faded away as

=> Metal M displaces Copper from Copper Sulphate solution as follow. :

M (s) + CuSO4(aq) ---------> MSO4(aq) + Cu (s)

=> Metal M is more reactive than Copper.

=> Type of Reaction : Single Displacement Reaction as one metal displace another.
