Intro to Chemistry

1. Intro to Chemistry

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

3. 6 Major Areas of Study • Organic Chemistry • Inorganic Chemistry • Biochemistry • Physical Chemistry • Analytical Chemistry • Theoretical Chemistry

4. Organic Chemistry • Chemistry of compounds that contain carbon • Found in living systems • Used in artificially made products C6H12O6 NaCl

5. InorganicChemistry • Chemistry of compounds that do NOT contain carbon • BaCl2 • NaOH • CH4 • Fe2O3 X

6. Biochemistry • Chemistry of organic compounds and the processes they go through Processes: -Photosynthesis -Krebs Cycle -Genetics Molecular: -Cell Structure -Cell Function

7. Physical Chemistry • Deals with physical properties of a material • Properties that can be measured • Examples: • Temperature • Freezing Point • Melting Point • Boiling Point • Density • Color

8. AnalyticalChemistry • Chemistry that defines the chemical composition of a material • Qualitative: What it is • Quantitative: How much there is

9. Theoretical Chemistry • Using math and computers to understand principles behind observed chemical behavior • Predict properties of new compounds

10. 3 Types of Research • Research is done for different reasons. The type of research pursued is dependent upon what information is important/needed

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

12. Applied Research The main goal of this type of research is to solve a specificproblem. • Example: CFC’s (chlorofluoro carbons) • in refrigerants destroyed the ozone so chemists formulated new refrigerants

13. Technological Development • This type of research involves the making and use of products that • improve the quality of life. • Development can result fromBasicResearch.
