CHY 121 General Chemistry I
First semester of a two-semester sequence covering fundamental principles in chemical science presented in quantitative terms. Topics include matter, chemical reactions, stoichiometry, thermochemistry, quantum theory, atomic structure, electronic configurations, periodic properties of elements, bonding theories, and molecular geometries. This course and CHY 123 (taken concurrently) provide the basis for further study of chemistry. If CHY 101 was taken at UMM, credit cannot be earned for this course.

CHY 123 General Chemistry Laboratory I
Introduction to experimental techniques and the process of scientific inquiry in chemistry. Emphasis is placed on making connections between macroscopic experimental observations and chemistry occurring at the atomic scale. Laboratory investigations are designed to help strengthen chemical understanding of concepts such as conservation of mass, limiting reactants, heats of reaction, greenhouse gases, chemical redox reactions, chromatography, and spectroscopy. CHY 123 is taken concurrently with CHY 121. If CHY 101 was taken at UMM, credit cannot be earned for this course.
