A chemical substance is any material with a definite chemical composition, no matter where it comes from.
[1] For example, a sample of water has the same properties and the same ratio of hydrogen and oxygen whether the sample is isolated from a river or made in a laboratory. A pure substance cannot be separated into other substances by any mechanical process,[2]. Typical chemical substances found in the home are water, salt (sodium chloride) and sugar (sucrose).
