- VI. Catalog Course Description
- This lecture and laboratory course introduces some basics of chemistry for students with inadequate preparation for Chemistry I. The development of skills for solving quantitative (numerical) problems is emphasized. Topics include measurement, basic chemical concepts and theories, and nomenclature of simple ionic and covalent compounds.
- VII. Required Course Content and Direction
This course is designed to meet the needs of science and engineering students who are academically unprepared for Chemistry I, a required course in their programs of study. These students generally have deficiencies in their chemistry and/or mathematics backgrounds. The course content has been carefully chosen to correct these deficiencies and to enable the student to complete Chemistry I successfully. Students must have completed Intermediate Algebra, MATH103, before enrolling in CHEM100. They must take College Algebra, MATH120, concurrently with this course if they have not already done so because they must develop their mathematical sophistication simultaneously with their study of chemistry in order to understand the chemical concepts presented.
In order to prepare students for Chemistry I, the major focus of the course is in solving quantitative problems based on chemical laws and principles. Students are given a review of basic arithmetic and algebraic methods used in Chemistry I as well as instruction in the use of the scientific calculator. Students are introduced to the metric system, to laboratory instruments used in the determination of the chemical and physical properties of matter, to scientific notation of chemistry including chemical symbols, chemical formulas, nomenclature, and chemical equations. Relative atomic and molecular weights and the mole concept are used in dealing with quantitative problems in stoichiometry. The use of the Periodic Law enables students to make valid predictions of the chemical behavior of the typical elements. Throughout the course students are expected to translate the laws and principles learned into mathematical relationships needed in the solution of quantitative problems dealing with chemical phenomena.
Chemistry, as one of the Natural Sciences, has evolved out of careful observation and experimentation; as technology evolves, so does the body of chemical knowledge. This course will integrate important technological advances and their impact in the formulation of chemical principles and their applications. Furthermore, the laboratory component of the course will help to illustrate and apply some of these technological advances.
In general, the lectures deal with the laws and principles of chemistry while the weekly recitation sessions provide opportunities for students to develop the skills needed for dealing with the quantitative solutions of chemical problems. The laboratory sessions provide hands-on experience with the tools of science and allow students to reinforce the theoretical considerations presented in lecture with observations in the real world.
