Answer 2

Explanation:

Displacement reaction is a reaction in which a higher reactive metal replaces a lower reactive metal . There are two types of displacement reactions 1) single displacement and 2) double displacement . Single displacement is when single metal is dispalced and double displacement is when two meatls displace other two metals

examples : Zn + CuSO4 = ZnSO4 + Cu

here Zn replaces Cu from CuSO4 ( single displacement reaction)

Na2SO4 + BaCl2 = BaSO4 + 2NaCl ( double displacement reaction)

here Na and Ba displace each other
