Answer:
Mixtures and compounds
Compounds are two or more elements chemically combined in definite proportions by weight. Mixtures are two or more substances not chemically combined.
Metals and non-metals
Difference Between Metals And Nonmetals. Metals and Nonmetals are different types of materials present around us. Metals (like copper and aluminium) are good conductors of heat and electricity, while nonmetals (such as phosphorus and sulfur) are insulators.
Elements and compounds
An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.
Distillation and fractional distillation.
Fractional distillation is essentially the same as simple distillation except that a fractionating column is placed between the boiling flask and the condenser. The fractionating column is usually filled with glass or plastic beads. These beads improve the separation between the liquids being distilled.
