A. What Is Chemistry?
* Because living and non-living things are made of matter, chemistry affects all aspects of life and most natural events. * Matter- is anything that has mass and occupies space.
* Chemistry- is the study of the composition of matter and the changes that matter undergoes. B. Areas of Study
* Five traditional areas of study are organic chemistry, inorganic chemistry, biochemistry, analytical chemistry, and physical chemistry. * Organic chemistry- defined as the studies of all the chemicals containing carbon * Inorganic chemistry- defined as the studies of all the chemicals that do not contain carbon * Biochemistry- is the study of the processes that take place in organisms * Analytical chemistry- is the area of study that focuses on the composition of matter * Physical chemistry- area that deals with the mechanism, the rate, and the energy transfer that occurs when matter undergoes a change C. Pure and Applied Chemistry
* Pure chemistry- is the pursuit of chemical knowledge for its own sake * Applied chemistry- is the research that directed toward a practical goal or application * Pure research can lead to an application, but an application can exist before research is done to explain how it works 1. Nylon
* Hermann Staudinger proposed that cotton and silk contained small units joined together like links in a chain 2. Aspirin
* By 1950, some doctors began to recommend a low daily dose of aspirin for patients who were at risk for a heart attack * Many heart attacks occur when blood clots block the flow of blood through arteries in the heart 3. Technology
* Technology- means by which a society provides its members with those things needed and desired D. Why Study Chemistry?
* Chemistry can be useful in explaining the natural world, preparing people for career opportunities, and producing informed citizens 1....
