Title: CLASSIFICATION OF MATTER


1
CLASSIFICATION OF MATTER
2
CLASSIFICATION OF MATTER
3
CLASSIFICATION OF MATTER
  • A substance that has constant composition and
    properties (contains only one kind of particle)
  • A substance that can be separated into parts
    based on a physical property (different kinds of
    particles)

4
PURE SUBSTANCES
5
ELEMENTS
  • a pure substance made up of 1 type of atom
  • cannot be broken down by ordinary means (using
    chemical reactions)

6
  • All elements are arranged on the periodic table.

7
PURE SUBSTANCES
8
COMPOUNDS
  • compound a pure substance that contains two or
    more different elements that are chemically
    bonded together.

9
COMPOUNDS
  • H2O

NaCl
C12H22O11

CLASSIFICATION OF MATTER
  • A substance that has constant composition and
    properties (contains only one kind of particle)
  • A substance that can be separated into parts
    based on a physical property (different kinds of
    particles)

11
MIXTURES
  • a substance that contains two or more different
    pure substances that are NOT chemically combined

12
TYPES OF MIXTURES
  • Homogeneous Mixtures
  • A mixture that has one phase. The components
    within the solution are not identifiable with the
    eye.

13
TYPES OF MIXTURES
Homogeneous Mixtures
  • Solute the particle that is present in smaller
    proportions. The dissolved particle.

Solvent the particle in larger proportion. The
substance in which the solute is dissolved.
Solution A mixture in which a solute is
dissolved in a solvent.
14
TYPES OF MIXTURES
Homogeneous Mixtures
sterling silver
steel
bronze
silver copper
iron carbon
copper tin zinc
  • alloy a homogeneous mixture of one or more
    metals

15
TYPES OF MIXTURES
  • Heterogeneous Mixtures
  • A mixture in which the different components are
    identifiable.

16
Describing Matter
Matter can be described be examining the
physical and chemical properties of a substance
17
Physical Properties
  • A physical property describes a characteristic of
    a substance that can be observed or measured
    (qualitatively or quantitatively)

18
Examples of Physical Properties
19
Chemical Properties
  • A chemical property describes the ability of a
    substance to change into a new substance/substance
    s
  • Ex) combustibility, reactivity with acids

20
Changing Matter
  • Matter can be converted in two main ways through
    either physical or chemical changes.

21
  • Physical change a change in the state or form
    of a substance without changing the identity of
    the substance. The particles in the substance do
    not change.

22
CHEMICAL CHANGE
  • Chemical change the change of a substance into
    one or more new substances with different
    properties. This occurs through a chemical
    reaction.

23
CHEMICAL CHANGE
  • Clue 1 colour change

24
  • Clue 2 a precipitate forms

25
  • Clue 3 bubbles of gas are produced

26
  • Clue 4 heat or light are produced or absorbed

27
CHEMICAL CHANGE
  • Clue 5 the change is difficult to reverse
