Competently discuss concepts and solve problems relating to: acid/base equilibria, buffers, acid/base titrations, solubility equilibria, principles of entropy and thermodynamics, electrochemistry, and nuclear chemistry.

Recognize and apply concepts and theories of basic physical or biological sciences.

Apply scientific methodology and demonstrate the ability to draw conclusions based on observation, analysis, and synthesis.

Demonstrate connections with other subject areas.

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.
