carbon atom mixture or pure substances why?
Answers
Answer:
this is your answer
Explanation:
Is carbon atom considered a pure substance? Why or why not?
A pure substance needs only be made up of only one kind of molecule or it could be an ionic or metallic solid made up only of the atoms in the empirical formula, not necessarily one kind of atom. It is possible to have pure carbon dioxide, pure water, pure oxygen gas pure NaCl solid and pure solid iron, in theory only. It’s literally impossible to ensure that every single atom or molecule of ‘something else’ is removed from anything.
Carbon dioxide and water are molecules made of two different kinds (elements) of atoms.
Oxygen gas is also molecular but it’s made up of only one kind (element) of

Yes, carbon dioxide is a pure substance not a mixture.
First consider the properties of a pure substance:
•made of only one type of atom or molecule
•has a well-defined melting point, boiling point, colour, odour, density and solubility.
Examples of pure substances include elements like iron, silver, mercury etc. And compounds like water, carbon dioxide, methane, vinegar.
Now consider the properties of a mixture:
•materials do not chemically combine
•varying physical and chemical properties
Examples of mixtures include mechanical mixtures like soil, solution mixtures like sugar in coffee, suspension mixtures like tomato juice, and colloid mixtures like milk or ketchup.
