Composition of Matter (What stuff is made up of)
WHAT IS CHEMISTRY???
ANDChanges that occur to that matter
By definition, Chemistry is the study of:
Chemistry is very practical and has many applications to everyday life.
Chemistry became a science because people are naturally curious!
Chemistry is broken into 6 major areas of study:
•Organic Chemistry
•Inorganic Chemistry
•Biochemistry
•Physical Chemistry
•Analytical Chemistry
•Theoretical Chemistry
There is overlap between these major areas of study so you can’t talk about one area of study without relating to another area.
Organic Chemistry
Chemistry of compounds that contain the element "carbon"
Found in living systemsUsed in artificially made products
oSucrose C6H12O6
oNaCl

Analytical Chemistry
•Chemistry that defines the chemical composition of a material
Qualitative = tells what it isQuantitative = tells how much there is
Physical Chemistry
Chemistry that deals with physical properties of a material
Properties that can be measuredGenerate data on the material
Examples:o Temperatureo Freezing Pointo Melting Pointo Boiling Pointo Densityo Volume
Biochemistry
Chemistry of organic compounds and
the processes they go through
ProcessesoPhotosynthesisoKrebs cycleoGenetics
Theoretical
Chemistry
Using mathematics and computers to understand principles behind chemical behavior and to predict properties of new compounds.
• Quantum mechanics – explaining the probability of finding electrons within the electron cloud.
Research is done for different reasons. The type of research pursued is dependent on what information is important / needed.
Basic or Pure Research: The main goal of this type of research is to gain new knowledge about a chemicalor process, just for the sake of knowledge.
Chance discoveries can result from basic research. “I wonder what would happen if…”
Applied Research: The main goal of this type of research is to solve a specific problem.
Example: CFC’s (chloro fluoro carbons) in refrigerants destroyed the ozone so chemists formulated new refrigerants.
