States Of Matter

19. Types of Mixtures - Name and define the two types of mixtures

Back 1

Heterogeneous - Mixture is made of different substances that remain physically separate.

Homogeneous - Mixture that is uniform in

composition throughout.

Front 2

20. What is Solution?

Back 2

Groups of molecules that are mixed and evenly distributed in a system. It is homogeneous.

Front 3

21. Solute vs. Solvent

Back 3

Solute - Substance to be dissolved (sugar).

Solvent - doing the dissolving (water).

Front 4

22. What is a saturated solution?

Back 4

Solution in which the maximum amount of solute has been dissolved.

23. Separating Mixtures

Back 5

Filtration - Used to separate a suspension mixture where small solid particles are suspended in liquid or air

Front 6

23. Separating Mixtures

Back 6

Density - Substances in a mechanical mixture have different densities, one substance may float and another may settle to the bottom (sand and wood chips - wood chips float and sand sinks).

Front 7

23. Separating Mixtures

Back 7

Distillation - Substance dissolves. It mixes completely with another substance (water, sand and salt (salt disappears).

Front 8

23. Separating Mixtures

Back 8

Evaporation - Solution to get a substance dissolved in it.

Front 9

23. Magnetism

Back 9

Separate a mechanical mixture if one of the substances in the mixture is attracted to a magnet.

24. Particle Arrangement Solid/Liquid/Gas - draw the particle arrangements for solids, liquids and gas

Front 11

25. Describe Particle Movement Solid/Liquid/Gas

Back 11

Solid - Packed closely together and fixed in one position. Vibrate in place.

Liquid - Packed closely together but move around freely.

Gas - Will move and spread apart.

Front 12

26. Shape Solid/Liquid/Gas - Describe the volume as either definite or indefinite

Back 12

Solids - definite

Liquid - indefinite

Gas - indefinite

Front 13

27. Volume Solid/Liquid/Gas - describe the volume as definite or indefinite

Back 13

Solid - definite

Liquid - definite

Gas - Indefinite

29. How can we have thousands of substances but only 100+ elements

Back 15

You can have a great number of atoms in any molecule, and an great number of ways to to put atoms together.

Front 16

30. Why can mixtures be separated using simple physical means, but compounds cannot be separated simply?

Back 16

Compounds are elements that are chemically bonded and can be separated only by chemical means.
