8. Composition of Matter (What stuff is made up of) WHAT IS CHEMISTRY??? AND Changes that occur to that matter By definition, Chemistry is the study of:

9. Chemistry is very practical and has many applications to everyday life. Chemistry became a science because people are naturally curious!

10. Chemistry is broken into 6 major areas of study: Organic Chemistry Inorganic Chemistry Biochemistry Physical Chemistry Analytical Chemistry Theoretical Chemistry

11. There is overlap between these major areas of study so you can’t talk about one area of study without relating to another area.

12. Organic Chemistry Chemistry of compounds that contain the element "carbon"  Found in living systems  Used in artificially made products o Sucrose C 6 H 12 O 6 o NaCl X

13. Inorganic Chemistry Chemistry of compounds that DO NOT contain “carbon” BaCl 2 NaOH CH 4 Fe 2 O 3 X

14. Analytical Chemistry Chemistry that defines the chemical composition of a material  Qualitative = tells what it is  Quantitative = tells how much there is

15. Physical Chemistry Chemistry that deals with physical properties of a material  Properties that can be measured  Generate data on the material  Examples: o Temperature o Freezing Point o Melting Point o Boiling Point o Density o Volume

16. Biochemistry Chemistry of organic compounds and the processes they go through  Processes o Photosynthesis o Krebs cycle o Genetics

17. 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.

18. Research is done for different reasons. The type of research pursued is dependent on what information is important / needed.

19. Basic or Pure Research: The main goal of this type of research is to gain new knowledge about a chemical or process, just for the sake of knowledge. Chance discoveries can result from basic research. “I wonder what would happen if…”

20. 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.

21. Technological Development: This type of research involves the making and use of products that improve the quality of life. Development can result from Basic Research. Examples: Teflon coating
