Chapter 1 Introduction to Chemistry I. Chemistry A. What is matter? 1. Chemistry is the study of the composition of matter and the changes that it undergoes. a) Matter is anything that has mass and occupies space. b) Because living and nonliving things are made of matter, chemistry affects all aspects of life and most natural events. B. Areas of Study 1. Five traditional areas of study are organic chemistry, inorganic chemistry, biochemistry, analytical chemistry, and physical chemistry. a) Organic chemistry is defined as the study of all chemicals containing carbon. b) Inorganic chemistry is the study of chemicals that, in general do not contain carbon. c) The study of processes that take place in organisms is biochemistry. d) Analytical chemistry is the area of study that focuses on the composition of matter. e) Physical chemistry is the area that deals with the mechanism, the rate, and the energy transfer that occurs when matter undergoes a change. C. Pure and Applied Chemistry 1. Pure chemistry is the pursuit of chemical knowledge for its own sake. 2. Applied chemistry is research that is directed toward a practical goal or application. 3. Pure research can lead directly to an application, but an application can exist before research is done to explain how it works.

a) Nylon and aspirin provide examples of these two approaches. 4. Technology is the means by which society provides its members with those things needed and desired. D. Why Study Chemistry? 1. Chemistry can be useful in explaining the natural world, preparing people for career opportunities, and producing informed citizens. a) read pages 10-11 II. Chemistry Far and Wide A. Materials 1. Chemists design materials to fit specific needs. 2. Two different ways of looking at the world are the microscopic view and the macroscopic view. B. Energy 1. Energy is necessary to meet the needs of a modern society. a) There are two ways to meet the demand for energy – conserve energy recourses and produce more energy. b) Chemists play an essential role in finding ways to conserve energy, produce energy, and store energy. Read page 13 C. Medicine and Biotechnology Chemistry 1. Chemistry supplies the medicines, materials, and technology that doctors use to treat their patients. a) Medicines – There are over 2000 prescription drugs. Many drugs are effective because they inte4ract in a specific way with chemicals in cells. Knowledge of the structure and function of these target chemicals helps a chemist design safe and effective drugs. b) Materials – chemistry can supply materials to repair or replace body parts.
