A pure substance is something that is only composed of one component. So, everything in the Periodic Table as well as every single molecule can be considered a pure substance.
For example, a block of sulfur is a pure substance because it's made entirely out of sulfur. Another example would be a cup of pure acetone because there is only acetone inside the cup.
So, salt water is not a pure substance because it's water mixed with salt.
chemical
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.

No, a pure substance would not settle out and form two distinct layers. This does not happen becuase pure substances such as hydorgen or H2O does not consist of many different substances that could settle out and seperate into two distinct layers. ~ Justin .A.
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.
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.
None of these are pure substances. All are mixtures.
Pure substances have identical particles. This means that all samples of a pure substance will have the same type and arrangement of particles, whether they are atoms, molecules, or ions. Examples of pure substances include elements and compounds.
