Why is some mixture is not a mixture but a pure substance?

Answer 1

Because it is the same throughout, in other words the "mixture" is made up of only one component ( the chemical substance). The chemical and physical properties of a substance formed together by 2 or more different elements are generally vastly different from the properties of the atoms in their elemental state. For example chlorine is a poisonous gas with an acrid odor and green color and sodium is a very soft and shiny metal with low melting point react to form sodium chloride which is inert, colorless, brittle and non conductive solid. Basically the properties of each component is unique and differentiates different chemical substances.

Answer 2

Some mixtures are considered to be pure substances when they contain only one type of element or compound. An example is a homogeneous mixture, like a solution of salt dissolved in water, where the components are so evenly distributed that they cannot be easily separated. In this case, the mixture behaves as a pure substance because its properties are uniform throughout.

Answer 3

Any substance that is not a mixture is a pure substance. :)

Answer 4

Every molecule is the same in an element and a compound, but not in a mixture. Elements and compounds have exact composition, mixtures do not.

Answer 5

it is because compound and elements have chemical reaction process or chemical means in it but mixtures do not

Answer 6

It can not see different parts of the mix unlike Pizza
