1 MATTER MIXTURES

2 MIXTURES Many substances in nature are not pure substances, instead they are mixtures.

3 A mixture is a combination of
two or more elements and/or compounds.

4 Lemonade water - liquid sugar - sweet lemons - sour
What does lemonade taste like? What is lemonade made of ? water - liquid sugar - sweet lemons - sour

5 AIR Nitrogen – N2 Oxygen – O2 Carbon dioxide – CO2

6 Marble calcite dolomite and other minerals

7 Lemonade The mixture has properties that are similar
to the components that make it up. Each component in the mixture retains its individual chemical properties.

8 MIXTURE ? ? Combination of elements and/or compounds Mixture of two
Mixture of an element and a compound ? ?

9 Pure substance or Mixture Composed of? elements

10 Pure substance or Mixture Composed of? elements

11 Pure substance Mixture Pure substance Pure substance Mixture Mixture

12 Pure substance Mixture Element compound

13 Pure substance Mixture

14 Pure substance or mixture?

15 Pure substance or mixture ?

16 Pure substance or mixture ?

17 Pure substance or mixture ?

18 Pure substance or mixture ?

19 Pure substance or mixture ?

20 Pure substance or mixture ?

21 Mixtures can be classified as heterogeneous mixtures or
homogeneous mixtures. Hetero = different Homo = same

22 A heterogeneous mixture is
one that doesn’t blend evenly throughout, individual substances remain distinct. granite

23 HETEROGENEOUS MIXTURES
minerals rock water air organic matter bacteria Pond water water algae protozoa mud bacteria Oil and vinegar soil

24 A homogeneous mixture is a mixture
that has the same composition throughout. Homogeneous mixtures are also referred to as solutions. It has a single phase.

25 HOMOGENEOUS MIXTURES - solutions
Air: gas - gas Soda pop: gas - liquid (nitrogen, oxygen, carbon dioxide) Water, sugar, flavoring, carbon dioxide

26 HOMOGENEOUS MIXTURES - solutions
Vinegar: liquid - liquid Kool-aid: liquid - solid (water, acetic acid) (water, sugar, kool-aid)

27 HOMOGENEOUS MIXTURES - solutions
14k gold: solid - solid (gold, copper) Coins: solid - solid (copper, nickel)

28 HOMOGENEOUS MIXTURES - solutions
24k gold is pure gold. 14k gold is 14/24 or 58.3% gold 14k gold: solid - solid (gold, copper)

29 There are two types of matter:
Pure substance --- element compound Combination of elements and compounds (2) Mixture--- hete

Example of Physical Change
Heterogeneous vs Homogeneous. Definitions: The prefix “homo” – indicate sameness Homogeneous – A homogeneous mixture has the same uniform appearance throughout.
