1. Description -
This course introduces one of the most significant emerging fields in modern chemistry, green chemistry, which connects the optimum use of chemistry to the well-being of humanity and the environment. Fundamental principles of chemistry necessary to understand the source and fate of man-made chemical substances in the environment and potential impacts on human health. Chemical concepts such as atomic structure, bonding, thermodynamics, and chemical reactivity are introduced as they pertain to particular environmental issues. Basic chemical laboratory techniques and methods are included as well as a survey of important green chemical principles with an emphasis on inquiry and problem solving. Intended for students who wish to meet general education requirements in physical science.
