Chemists prefer the expression pure substance.
No, the difference between a pure substance and a mixture is not always easy to observe. While pure substances have definite chemical compositions and properties, mixtures consist of two or more substances physically combined. Some mixtures can be challenging to distinguish from pure substances based on visual observations alone.
Yes, pure substances can dissolve in certain solvents or environments. The solubility of a pure substance depends on the interactions between the molecules of the substance and the molecules of the solvent.
it is a pure substance.... not
Methane is a pure substance.
pure substance
The difference between a homogeneous mixture and a pure substance is that a pure substance has a fixed composition and cannot be separated because it is chemically bonded and a homogeneous mixture can be separated.
No.
A pure substance is one which contains only that substance and nothing else. An impure substance contains other substances in varying amounts.
an atom is the smallest unit of an element, but an element is a pure substance
An element is a pure material substance, a convention is a meeting of people.
A pure substance has only one kind of atom or molecule.A mixture has a number of different pure substances mixed together.
A pure substance has a specific density that remains constant regardless of the amount of substance present. An impure substance may have a density that varies depending on the amount and type of impurities present in the substance.

Air is a mixture.
Glass is a clear substance, i.e. you can see through it. But it may also have germs and bits of dirt on it and therefore not be clean.
A mixture is a substance composed of two or more components physically combined. An element is a pure substance composed of one kind of atom. A compound is a pure substance formed when atoms of two or more elements chemically combine.
the difference is that a solution is a mix and a mechanical mix is solo there two different things so maybee learn more........
