Chemistry
  • The study of matter and the changes it undergoes.

3
Scientific Method
  • A systematic approach to solving problems.

4
Matter
  • Anything that has mass and takes up space.

5
Matter
  • Atoms are the building blocks of matter.

6
Matter
  • Atoms are the building blocks of matter.
  • Each element is made of the same kind of atom.

7
Matter
  • Atoms are the building blocks of matter.
  • Each element is made of the same kind of atom.
  • A compound is made of two or more different
    kinds of elements.

Properties and Changes of Matter
21
Properties of Matter
  • Physical Properties
  • Can be observed without changing a substance into
    another substance.
  • Boiling point, density, mass, volume, etc.
  • Chemical Properties
  • Can only be observed when a substance is changed
    into another substance.
  • Flammability, corrosiveness, reactivity with
    acid, etc.

22
Properties of Matter
  • Intensive Properties
  • Independent of the amount of the substance that
    is present.
  • Density, boiling point, color, etc.
  • Extensive Properties
  • Dependent upon the amount of the substance
    present.
  • Mass, volume, energy, etc.

23
Changes of Matter
  • Physical Changes
  • Changes in matter that do not change the
    composition of a substance.
  • Changes of state, temperature, volume, etc.
  • Chemical Changes
  • Changes that result in new substances.
  • Combustion, oxidation, decomposition, etc.

24
Chemical Reactions
  • In the course of a chemical reaction, the
    reacting substances are converted to new
    substances.

25
Chemical Reactions
26
Compounds
  • Compounds can be broken down into more elemental
    particles.

27
Electrolysis of Water
28
Separation of Mixtures
29
Distillation
  • Separates homogeneous mixture on the basis of
    differences in boiling point.

30
Distillation
31
Filtration
  • Separates solid substances from liquids and
    solutions.

32
Chromatography
  • Separates substances on the basis of differences
    in solubility in a solvent.

33
Units of Measurement
34
SI Units
  • Système International dUnités
  • Uses a different base unit for each quantity
