Colloidal suspensions are heterogeneous; they necessarily contain more than one substance. You could make one out of two pure substances.
Pure substances are made up of a single element, or a single compound. Table salt is a pure substance because it is made up of only the compound NaCl (sodium chloride). Diamond is a pure substance, it is made up of the element carbon. Air is not a pure substance, it is a mixture of several gaseous elements and compounds (nitrogen, oxygen, carbon dioxide..) Distilled water is a pure substance made up of a single compound H2O.

While studying matter, we were able to break it down to the point where it could not be broken down any further. We were left with Pure substances and mixtures. Here we were able to identify what elements were and what they could make. Scientists define matter as pure substances that cannot be decomposed.
Pure substances that are physically combined make a mixture.
pure are you dumb or something
Pure substances are divided into elements and compounds.
Practically (exceptions exist) all known substances can be obtained in a pure fom.
Compounds and solutions are pure substances
The characteristics of pure substances are:fixed melting pointfixed boiling pointsfixed valencyfixed densitystability
Yes, compounds are pure substances.
Matchbox are not pure substances.
Nope . It's a mixture of many pure substances
Pure matter substances can be elements, compounds, or mixtures where all components are the same throughout. Examples include pure water (H2O), pure iron (Fe), and pure table salt (NaCl).
A mixture contain two or more pure substances.
Yes my friends. All elements are pure substances that cannot be broken down. However, pure substances aren't all elements.
