What are some
different ways to
classify matter?
In Chemistry one way we useIn Chemistry one way we use
isis::
Elements
Compounds
Mixtures
Element - a substance
that cannot be broken
down by chemical
methods
Examples- anything on
the periodic table
Compound - a
substance composed
of two or more
elements bonded
together, always in the
same ratio
Law of Definite
Proportions - a
chemical compound
always has the same
ratio of elements (by
how many and their
mass) ex. H...
Examples of compounds:Examples of compounds:
Salt (NaCl)
Sugar (C6H12O6)
Carbon dioxide (CO2)
Dinitrogen monoxide (N2O)
Compounds can be
broken down into
elements by chemical
methods (breaking
bonds)
Substance (or pure
substance) -
has the same
composition, must be
either a pure element
or a pure compound
Mixture - a combination
of two or more
substances (elements or
compounds), can be
combined in any ratio
(variable composit...
Two types of mixtures:
Homogeneous Mixture
or Solution -
always the same
throughout, no matter
where you take a
sample
Examples -
salt water, air, alloys,
soda
Note - Solutions don’t
have to be liquids!
Heterogeneous
Mixture - contains
parts that have
different properties
and composition
Examples -
Pizza, ice cream
sundaes, sand and
water

Transcript of "Matter part 1 types 2013"

  1. 1. Matter – Part 1Matter – Part 1
  2. 2. What are some different ways to classify matter?
  3. 3. In Chemistry one way we useIn Chemistry one way we use isis:: Elements Compounds Mixtures
  4. 4. Element - a substance that cannot be broken down by chemical methods Examples- anything on the periodic table
  5. 5. Compound - a substance composed of two or more elements bonded together, always in the same ratio
  6. 6. Law of Definite Proportions - a chemical compound always has the same ratio of elements (by how many and their mass) ex. H2O has 2 hydrogen 1 oxygen
  7. 7. Examples of compounds:Examples of compounds: Salt (NaCl) Sugar (C6H12O6) Carbon dioxide (CO2) Dinitrogen monoxide (N2O)
  8. 8. Compounds can be broken down into elements by chemical methods (breaking bonds)
  9. 9. Substance (or pure substance) - has the same composition, must be either a pure element or a pure compound
  10. 10. Mixture - a combination of two or more substances (elements or compounds), can be combined in any ratio (variable composition)
  11. 11. Two types of mixtures:
  12. 12. Homogeneous Mixture or Solution - always the same throughout, no matter where you take a sample
  13. 13. Examples - salt water, air, alloys, soda Note - Solutions don’t have to be liquids!
  14. 14. Heterogeneous Mixture - contains parts that have different properties and composition
  15. 15. Examples - Pizza, ice cream sundaes, sand and water
