Explanation:

First, 4 common mixture separation methods are described. Then, for each mixture in the chart, the separation mechanism and the key physical property enabling separation are identified based on standard chemistry principles.

Answer:

4-5 Different Ways to Separate Mixtures:

1. Magnetic Separation: Use a magnet to pull out magnetic components from non-magnetic ones in a mixture.
2. Filtration: Pass a mixture through a porous barrier to trap solid particles and let liquid/gas pass through.
3. Evaporation: Heat a solution to turn the liquid solvent into vapor, leaving dissolved solid solute behind.
4. Hand Sorting: Physically separate distinct, large components of a heterogeneous mixture by hand.

Completed Separation Chart:

Mixture	Separation Mechanism	Physical Properties that Allow Separation
2. Salad	Hand Sorting	Components are large, distinct solids
3. Salt and Water	Evaporation	Water has a low boiling point; salt has a high boiling point (does not vaporize with water)
4. Muddy Water	Filtration	Mud particles are large enough to be trapped by filter paper; water is a small liquid molecule
5. Dust in Air	Filtration (using an air filter)	Dust particles are larger than the pores in the air filter; air molecules are small enough to pass through
