What is a solution
Definition of a solution: the process by which a gas, liquid, or solid is spread throughout homogeneously in a gas, liquid, or solid without chemical change. - a homogeneous, molecular mixture of two or more substances.

name 1 way to separate a mechanical mixture and explain how it is done?
sifting: it involves shaking a solid material through a screen Filtration:the mixture is poured in the filter Magnetism:some metals are magnetic so we put a metal over the metal. sorting : separating substances on the basic of appearances
