VI. Catalog Course Description
In this lecture and laboratory course the chemical principles covered in a qualitative manner in Chemistry A (CHEM101) are reviewed quantitatively. The study of important topics in Organic and Biological Chemistry is enhanced. Polymer Chemistry and Industrial Syntheses are introduced.
VII. Required Course Content and Direction

Chemistry B is designed to serve as a second semester general chemistry course for the non-science major. The chemical principles covered in Chemistry A (CHEM101) were dealt with largely in a qualitative manner. Chemistry B will cover some selected areas of this material in a quantitative manner, but not in as much detail as General Chemistry for science majors. Chemistry B will also amplify many of the Organic and Biochemical areas discussed in Chemistry A to help the students understand the application of chemical concepts learned in Chemistry A to biological systems.

As one of the Natural Sciences, chemistry has evolved out of careful observation and experimentation; as technology evolves, so does the body of chemical knowledge. This course will integrate relevant 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.

The topics include the use of quantitative measurements in chemical equations, understanding of equilibrium concepts, and a quantitative review of solution chemistry and acid-base theory. The study of organic compounds introduces the general preparation and properties of the major classes of functional groups. Structure and characteristics of the organic compounds that constitute the biomass (lipids, carbohydrates, proteins, nucleic acids, etc.), with an emphasis on their metabolic fate will be included. Polymer chemistry and industrial chemistry are also studied.

  1. Course Learning Goals

    Students will:

    1. demonstrate basic problem solving skills dealing with quantitative measurements generally used in chemical, medical and biological laboratories;
    2. discuss matter and transformations of matter, including states of matter, chemical reactions, balancing chemical equations, chemical bonding, intermolecular forces, acids and bases, oxidation reduction reactions, chemical equilibrium;
    3. identify the major classes of functional groups in organic chemistry and their critical role in biological systems (as proteins, carbohydrates, lipids, etc.) and their reactions as related to metabolism;
    4. demonstrate proficiency in laboratory skills as they pertain to: chemical information, safe handling, use and disposal of organic compounds; synthetic procedures; and stoichiometry; and
    5. recognize the industrial processes required for the preparation of some compounds such as ammonia or sulfuric acid.
