Answer 2

Answer:

Iron+ copper sulphate---> Iron sulphate + copper

Zinc + copper sulphate---> Zinc sulphate + copper

Lead + copper chloride---> Lead chloride + copper

Copper + silver nitrate----> Copper nitrate + silver

Explanation:

Iron+ copper sulphate---> Iron sulphate + copper

Zinc + copper sulphate---> Zinc sulphate + copper

Lead + copper chloride---> Lead chloride + copper

Copper + silver nitrate----> Copper nitrate + silver

These all are examples of displacement reaction where more reactive metal displaces the less reactive metal.

Iron is more reactive than copper

Zinc is more reactive than copper

Lead is more reactive than copper

Copper is more reactive than silver
