Intro to Chemistry
What is Chemistry???• By definition, Chemistry is the study of:
Composition of Matter(What stuff is made up of)
ANDChanges that occur to that matter
6 Major Areas of Study•Organic Chemistry
•Inorganic Chemistry•Biochemistry
•Physical Chemistry• Analytical Chemistry•Theoretical Chemistry
Organic Chemistry
• Chemistry of compounds that contain carbon– Found in living systems – Used in artificially made products
C6H12O6 NaCl
InorganicChemistry
• Chemistry of compounds that do NOT contain carbon
•BaCl2•NaOH•CH4
•Fe2O3
X
Biochemistry
• Chemistry of organic compounds and the processes they go throughMolecular:-Cell Structure-Cell Function
Processes:-Photosynthesis-Krebs Cycle-Genetics
Physical Chemistry
• Deals with physical properties of a material– Properties that can be measured
Examples:oTemperatureoFreezing PointoMelting PointoBoiling PointoDensityoColor
AnalyticalChemistry
• Chemistry that defines the chemical composition of a material
• Qualitative: What it is• Quantitative: How much there is
Theoretical Chemistry
• Using math and computers to understand principles behind observed chemical behavior
• Predict properties of new compounds
3 Types of Research
• Research is done for different reasons. The type of research pursued is dependent upon what information is important/needed
Basic or Pure ResearchThe 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 ResearchThe 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
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.
