Mixtures- mix Vs Substances

Question 1

Centrifugation

Answer 1

Mixture is spun at high speeds creating a force which pulls heavier solid particles towards the bottom of the container

Question 2

Chromatography

Answer 2

The mixture is applied to a solid support and separated into its components by a solvent which carries the various components up the solid support at different rates

Question 3

Crystallization

Answer 3

The mixture is concentrated and cooled until the solid component slowly forms at the bottom of the container

Question 4

Electrolysis

Answer 4

Process where an electric current is applied to a sample, decomposing the sample into its component element

Question 5

Filtration

Answer 5

Solid component of mixture becomes trapped in a s screen? Allowing liquid to pass

Question 6

Floatation

Answer 6

Chemical added to a mixture, air is forced through the mixture.

Question 7

Settling

Answer 7

Components of a mixture separate into layers on their own

Question 8

Pure substance

Answer 8

Only one type of compound
Cannot be separated physically
Physics and chemical properties

Question 9

Mixture

Answer 9

More than one compound
Can be separated physically
Chemrica and physics properties change

Question 10

Mechanical mixture

Answer 10

Heterogenous mixture

Separated using mechanical seperation (phyidglwlinf using hands or magnets)

Question 11

Difference between homogenous and heterogenous material

Answer 11

Homogenous is the same throughout no vidbale difference

Heterogenous is different in composition visbale difference
