Question

a reaction in which a more reactive metal displaces a less reactive metal from its salt solution

Answer 1

it's a displacement reaction .Eg; CuSo4 + Fe -------------- FeSo4 + Cu

Answer 2

Answer:

A displacement reaction happens when a more reactive metal (one that forms positive ions more easily) displaces a less reactive metal from a compound. Example: Magnesium is more reactive than copper, so magnesium can displace copper from a copper sulfate solution to create magnesium sulfate
