Physical Properties Chemical PropertiesDescription

Examples:

Know the difference between elements, compounds and mixtures:Elements Compounds Mixtures

Description

(know the relation of atoms, chemical bonds and molecules)

(know the relation with the chemical formula)

Examples Homogeneous vs. Heterogeneous (solution)

Howe can you separate a mixture?

Section 2: Changes in Matter (pp.68- 72 in your book) Know the difference between physical and chemical changes

Physical Changes Chemical ChangesDescriptionExamples:

Combustion:

Electrolysis:

Oxidation:

Tarnishing:

Important: Unlike a physical change, a chemical change produces new substances with properties different from those of the original substances Describe the law of conservation of matter:

Section 3: Energy and Matter (pp.73 -76 in your book) Describe energy: Know that the forms of energy related to changes in matter include thermal

energy, chemical energy, electromagnetic energy, and electrical energy:Thermal energy

Description Endothermic change:

Exothermic change:

Examples

Be able to read the following graph and answer the questions below: Endothermic Change: Exothermic Change:

Description

Examples:

Know that during a chemical change, chemical energy may be changed to other forms of energy. Other forms of energy may also be changed to chemical energy.

o Example: Photosynthesis

-Is this a physical or chemical formula? -How do you know?

-Is this an endothermic or exothermic change?

-Describe what kind of energy transformation occurs during photosynthesis:
