__What is chemistry?__ Key Concept: Because living and nonliving 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 it undergoes. __Areas of Study__ Key Concept: Five traditional areas of study are organic chemistry, inorganic chemistry, biochemistry, analytical chemistry, and physical chemistry. -Organic chemistry is the study of all chemicals containing carbon (with a few exceptions) -Inorganic chemistry is the study of chemicals that, in general, do not contain carbon -Biochemistry is the study of processes that take place in organisms (including muscle contraction, digestion, etc.) -Analytical chemistry is the area of study that focuses on the composition of matter -Physical chemistry is the area that deals with the mechanism, the rate, and the energy transfer that occurs when matter undergoes a change -the boundaries between each category are not firm, therefore chemists usually study in multiple areas at any given time __Pure and Applied Chemistry__ Key Concept: Pure research can lead directly to an application, but an application can exist before research is done to explain how it works - Pure Chemistry is the pursuit of chemical knowledge for its own sake - Applied Chemistry
 * does not have to be seen; example: air
 * can explain different aspects of our life / in the world
 *  found mainly in non-living things
 *  example: measuring the level of lead in drinking water
 * done to answer a specific question
