RECALL:
A mixture is the (physical / chemical) combination of 2 or more ____________.
Compounds are the ( chemical / physical) combination of 2 or more __________.
Mixtures can be broken into two more classifications: ________________ & ________________
Compounds can only be separated (physically / chemically)
Mixtures can only be separated (physically / chemically)

J. SEPARATING MIXTURES
FiltrationSeparates a solid from the liquid in a heterogeneous mixture using a porous barrier.
Example: A colander is used to separate pasta from the water in which it was cooked.

J. SEPARATING MIXTURES CONT. Distillation
Separates mixtures based on difference in boiling points of components in the mixture.
A liquid is boiled to produce a vapor that is then condensed into a liquid.Example: Distilled Water

J. SEPARATING MIXTURES CONT.
CrystallizationSeparates mixtures by forming pure solid particles in a solution containing the dissolved solute.
Example: Rock candy.

ChromatographySeparates the
components of a mixture because components travel across a surface at different rates.
