Catalog Course DescriptionScience and engineering majors take this lecture and laboratory course to study fundamental theories and principles of chemistry. Topics include stoichiometry, atomic/ molecular structure, bonding, states of matter, changes of state, and solutions. A quantitative study of each area is stressed; a strong background in chemistry and mathematics is required.
Required Course Content and DirectionChemistry 121(General Chemistry I) is a college level chemistry course for Science and Engineering majors. Students intending to transfer to a four-year institution will complete their basic level chemistry requirements with Chemistry 121 and Chemistry 122 (General Chemistry I and II).
Students intending to take this course require a background in chemistry, such as the one provided by a General Chemistry program in high school or any other introductory chemistry course. Students should be familiar with the elements, their symbols and the periodic table. Students should have a basic understanding of the properties of matter, and chemical reactions, including stoichiometry, in order to succeed in this course. Students will need to apply the concepts learned in College Algebra in Chemistry 121.
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 important technological advances and their impact in the formulation of chemical principles and their applications. The laboratory component of the course will help to illustrate and apply some of these technological advances.
Chemistry I is a qualitative and quantitative study, both in the classroom and the laboratory, of matter and energy as they relate to the chemical properties of solids, liquids, gases, and solutions. These properties are correlated with atomic structure, chemical bonding and the periodic law. Certain conceptual models, such as atomic orbitals, ideal gases, solutions, and the mole are utilized to predict the chemical properties of real systems.
- Course Learning Goals
- apply mathematical concepts and methods to chemical phenomena and to chemical problems;
- recognize the basic vocabulary and notation of chemistry, develop an awareness of the origin of scientific knowledge, and realize the importance of experimental verification of such knowledge;
- demonstrate an understanding of some of the basic theories and concepts of chemistry and be able to use these in verbal, mathematical, and graphical representations. These include:
- the atomic theory
- relative atomic weights and the mole
- chemical bond: ionic and covalent bonds
- density, percentage, molarity, and dilution;
- demonstrate an understanding of the following laws governing chemical phenomena, and be able to apply these laws to the solution of qualitative and quantitative problems:
- conservation of mass
- law of definite composition
- law of multiple proportions
- the periodic law and the Aufbau Principle
- gas laws; and
- demonstrate basic laboratory skills as they pertain to: safety, management of both qualitative and quantitative work, ability to draw conclusions from experiments, and understanding the importance of technological advances and scientific knowledge.
- Core Learning Goals
- accurately translate descriptive problems into mathematical formulas and solve them (1).
- apply the scientific method by explaining and identifying its components in a variety of situations (2).
- evaluate and graph data (1).
