Answer:
Particles that keep their own separate identities like rain drops are considered to be mixtures.
Explanation:
When two or more different compositions are mixed together, they can be form mixture and compound. The difference between mixture and compound is that in mixture each particle will be having their own separate identities. While in compound the particles will get diffused in each other forming a completely new material with new identities. Thus, if particles keep their own separate identities like rain drops, then those particles are said to form mixtures and not compounds.
