Elements
Pure Substances that cannot be broken down into other pure substances.
Compounds
A pure substance made of two pure substances. Can combine with element to form new substances.
Mechanical Mixture
A mixture with two or more part that can be easily seen.
Suspension
Murky mixture where mucks of solids or liquids are spread throughout a liquid or gas.
Solution
A mixture that appears to be only one substance but is made up of two or more substances that can only be seen under a microscope.
Emulsion

Concentration
A solution with a higher amount of solute dissolved in the solvent makes it more concentrated.

Solute
A substance that dissolves in the solvent.
Solvent

When no more of the solute can be put in the put in the solvent because it is too saturated.
Unsaturated
Able to dissolve more solute into the solvent.
Supersaturation
Solvent is able to hold more solute than it should be able to, should be a solid but remains a liquid.
MUST KNOW!!!
Matter= Mixtures or Pure Substances.
Pure Substances= Element or Compounds.
Mixtures= Mechanical mixture, Suspension or Solution.
