Course Description

A general chemistry sequence for students who have had no previous training in chemistry and for those whose college aptitude test scores indicate the need for a more elementary introduction to chemistry. Entering students are expected to have a working knowledge of high school algebra, logarithms, and scientific notation. Lec/lab/rec. (CH 122, CH 123 are Bacc Core Courses)

Course Credits

This course combines approximately 150 hours of instruction, online activities, and assignments for 5 credits.
 

Course Learning Outcomes

Students will be able to competently discuss concepts and solve problems relating to: matter and biomeasurement, the language of chemistry, atomic structure and electron configuration, bonding and molecular structure (including Lewis structures), solutions and concentration, and stoichiometry.

Communication

Please post all course-related questions in the Q&A Discussion Forum so that the whole class may benefit from our conversation. Please contact me privately for matters of a personal nature. I will reply to course-related questions within 24-48 hours. I will strive to return your assignments and grades for course activities to you within about five days of the due date.
