1. Chemistry Definition:
Study of the structure and properties of matter and energy and how they react and how it can be applied

2. FIELDS OF CHEMISTY Biochemical Processes of the Living
Physical Behavior &Changes of matter and energy
Analytical Components and Contents of Substances
Biochemical Processes of the Living
Organic Chemicals With Carbon
Inorganic Chemicals W/O Carbon
Nuclear Reactions of the Atom’s Nucleus

3. MATTER Definition: ANYTHING THAT HAS MASS AND TAKES UP SPACE (Volume)
CONTAINS THE PROPERTY OF INERTIA
INTERTIA – Newton’s 1st Law of Motion - An object in motion tends to stay in motion and an object at rest tends to stay at rest unless acted upon by an outside force

4. ENERGY: The Ability to Do Work
Types of Energy:
Kinetic Energy of Motion
Dependent on mass and speed of object EX:
Potential Energy “at rest”
Dependent on mass and position of object
EX:

5. Other Types of Energy Light (electromagnetic) Thermal (heat)
Electrical (electricity)
Nuclear
Chemical
Gravitational

6. RULES OF CHEMISTRY ASSUMPTION The Universe is A Closed System
therefore
amount of matter must stay the same
amount of energy must stay the same

7. Laws of Conservation Two Laws (but really just one):
1) Law of Conservation of Mass - matter can not be created or destroyed - it only changes form
EX:
2) Law of Conservation of Energy - energy can not be created or destroyed - it only changes form
Law of conservation of mass-energy: mass and energy are essentially one and the same - change into one another, but the total remains constant

8. QUIZ Areas of Chemistry: - making plastics from oil
