Asked by littykittykat9924

Answer (1)

Definitions: (a) Compound : A compound is a substance made up of two or more different types of atoms bonded together in a fixed proportion.

(b) Crystallization : Crystallization is a process by which a solid forms, where the atoms or molecules are arranged in a highly ordered structure, typically forming crystal shapes.
(c) Decantation : Decantation is a method for separating mixtures by pouring off a liquid to leave the sediment or insoluble solids behind.
(d) Distillation : Distillation is a technique for separating components of a mixture based on differences in their boiling points, by boiling the liquid and then condensing the vapor.
(e) Filtration : Filtration is a method for separating solids from liquids or gases using a filter medium that allows only the fluid to pass through.

Matching Column A with Column B: (a) Gas in gas: (vi) Air

(b) Gas in liquid: (v) Aerated water (soda)
(c) Liquid in liquid: (iv) Lemon juice in water
(d) Solid in liquid: (iii) Sea water
(e) Solid in solid: (ii) Soil
(f) Solid in gas: (i) Smoke
