Question

mixture separations

1. distillation separates mixtures based on _.
2. filtration separates mixtures based on _.
3. chromatography separates mixtures based on _.
4. mixtures can be separated through _ changes, which means no chemical bonds are broken or formed.

Explanation:

1. Distillation uses differences in boiling - points to separate mixtures.
2. Filtration separates based on particle size; larger particles are retained by the filter.
3. Chromatography separates based on the different affinities of substances for a stationary phase and a mobile phase.
4. Physical changes are used to separate mixtures without altering chemical bonds.

Answer:

1. Boiling - points
2. Particle size
3. Affinities for stationary and mobile phases
4. Physical
