A chemical substance is composed of one type of atom or molecule. A mixture is composed of different types of atoms or molecules that are not chemically bonded.

How are mixtures separated from their individual components?

A mixture’s physical properties, such as its melting point, may differ from those of its individual components. Some mixtures can be separated into their components by physical (mechanical or thermal) means. Chemistry 1.2 Classifying Matter (Part 1 of 3) – YouTube Introduction to classifying matter as a substance or a mixture of substances.
