Verified step by step guidance1
Understand the definition of a compound in chemistry: A compound is a substance formed when two or more different elements are chemically bonded together in fixed proportions.
Recognize that mixtures, such as solutions or physical blends, consist of substances combined physically and can be separated by physical means, so they are not compounds.
Note that a pure substance consisting of only one type of atom is an element, not a compound.
Identify that a solution is a type of mixture where a solute is dissolved in a solvent, which again is not a compound because the components are not chemically bonded.
Conclude that the best description of a compound is 'A substance composed of two or more elements chemically combined in fixed proportions.'
