3. constant composition (what it is made up of is the same everywhere)
Substance
Matter that has a
constant composition (what it is made up of is the same everywhere)

4. Element

Can be found on the period table!

Helium

5. Compound
A substance that has two or more different elements. Ratio is fixed.
Can be decomposed chemically.

6. Mixture A physical combination of two or more substances.
Each substance keeps its original properties. Can contain different types of matter.
Can be separated by physical means.

7. Heterogeneous Mixture
A mixture that is not constant in composition. Can see/identify the individual parts.

8. Homogeneous Mixture A mixture that looks constant throughout.
Also called solutions
Bronze
(Copper + Tin)

9. Distillation
A process for separating mixtures by evaporating a liquid from a solid or boiling and condensing liquids to separate them.

10. Separation by Filtration
