PURDUE UNIVERSITY Study Guide for CHEM I (Chemistry 115) This study guide describes the topics that should be mastered before you attempt the examination for credit in Chemistry 115. The material can be found in a number of books on the market. A list of possible textbooks is given below. ******************************************************************************* IMPORTANT: 1. Read this material thoroughly if you expect to try for advanced placement and extra credit which counts towards graduation. 2. Study the material listed in the outline. 3. Work as many practice problems as possible. 4. When you feel prepared to take the test-out exam, try the sample exam at the end of this study guide first. 5. Come to the examination rested and confident. ******************************************************************************** The subject matter of a general chemistry course varies somewhat from institution to institution. Chemistry 115 at Purdue University deals with chemical formulas, chemical equations, and the mole concept; chemical calculations including gram-mole and gram-gram calculations; the properties of gases and the kinetic molecular theory of gases; the properties of liquids and solids; periodic chemistry; electrons in atoms and molecules; and the energetics of chemical reactions. Many of these concepts are closely related. The mole concept is used extensively in studies of liquids, gases, and solids, while an understanding of electronic structure is essential for discussions of periodic chemistry, chemical bonding, oxidation and reduction reactions, and molecular geometry. The topics presented in this outline should be studied before you attempt the sample exam at the end of this study guide. These topics are listed under headings according to those found in the text currently in use at Purdue. They may not appear in exactly this order in the textbook you study. In preparing for the examination it is important to work as many problems as possible. The purpose of these problems must be understood, however. They should be used to measure your understanding of the concepts and principles involved, and not to test your ability to recall formulas or facts. Our examinations are designed to test whether you understand concepts rather than whether you remember formulas such as P 1 V 1 = P 2 V 2 . Knowledge of a limited number of equations, a clear under-standing of what they mean and how they can be used, and an understanding of definitions of basic concepts such as the mole, density, pressure, etc., should be sufficient to handle the vast majority of the problems encountered. At the end of this study guide you will find a sample examination. Allow 90 minutes for the exam. The exam does not cover every point in the outline, since no examination can do that. However, if you have no difficulty with the sample exam, you should not have any difficulty with the examination for credit. The answers to the exam are given on the last page of this Study Guide.
