1. The Nature of Chemistry
Chapter 1
The Nature of Chemistry

2. What is Chemistry?
Is the study of the composition of matter and the changes they undergo.
Matter
Anything that takes up space and has mass.
Mass
Amount of matter in a substance.
Substance
Is any matter or chemical that can undergo a change.
Weight
Force of attraction due to gravity.

3. Section 2 – Matter & Central Science
Chemistry is the Central Science.
It overlaps many other sciences, do to the fact that everything is made up of chemicals.

4. Branches of Chemistry Five major branches of chemistry:
Organic chemistry
Living or once living material, contain Carbon and Hydrogen.
Inorganic chemistry
Nonliving material, metals, plastic, minerals, etc.
Analytical chemistry
Qualitative and Quantitative study of matter.
Physical chemistry
Energies within the atoms and subatomic particles.
Biochemistry
Chemistry within living organisms.

5. Which Branch?
Determine which branch of Chemistry is most appropriate to the study:
Study of the respiration in fish.
Amount of mercury levels within fish at in the Allegheny river.
Process of converting crude oil into motor oil.
Determining the energy of a single electron.
Improving the hardness of steel.

6. Section 3 - Scientific Method
Steps of the Scientific Method
Observation
Hypothesize
Experiment
Conclude (Theory)
Natural Law – helps to describe how nature behaves but does not explain why nature behaves in that particular way.
Theory – statement explaining how things occur in relationship to the natural law. Can still be proven wrong. “superhypothesis”

7. Section 1.4 Safety in Laboratory
Follow teacher’s directions.
Notify teacher of problems.
Know how to use the safety equipment.
Emergency eyewash and shower.
Wear safety goggles.
Tie back long hair and loose clothing.
If it’s hot, let it cool.
Carry chemicals with caution.
Dispose of chemical waste properly.
Clean Up!!!

9. Section 4- Two types of chemical research
Applied Chemistry- use the knowledge of chemistry in their profession.
Nuclear Submarine engineer, Teacher, Pharmacist, etc.
Pure Chemistry- use the knowledge to discover new information on chemistry.
Scientist studying the depletion of ozone, or any scientific unknowns.
Dark Matter
