General Chemistry I
Major topics will include atomic theory and atomic structure; chemical bonding; stoichiometry; introduction to chemical thermodynamics. States of matter; solutions and nuclear chemistry. Laboratory work deals with testing of theories by various quantitative methods. Students with strong secondary school preparation are encouraged to consult the department chair for permission to elect CHEM 0104 or CHEM 0107 in place of this course. CHEM 0103 is also an appropriate course for a student with little or no prior preparation in chemistry who would like to learn about basic chemical principles while fulfilling the SCI or DED distribution requirement. Students with AP Chemistry scores of 4 or 5 OR Chemistry Placement scores of 21 or higher are NOT allowed to enroll in CHEM 103. Students MUST have taken the Chemistry placement exam and earned a score of 20 or less. 3 hrs. lect., 3 hrs. lab, 1 hr. disc.

Chemistry of Energy Conversion
With global energy use on the rise, it is essential to understand the different energy systems that are currently in place and how they can, or in many cases, cannot meet the world’s future energy demands in a sustainable manner. In this course we will begin with a brief overview on the energy sources themselves: potential energy (hydro), kinetic energy (wind, tidal), thermal energy (geothermal, ocean thermal), radiant energy (solar), chemical energy (oil, coal, gas, biomass), and nuclear energy (uranium, thorium). Once we understand the energy sources, we will apply the tools of inorganic chemistry (simple bonding, symmetry, transition metal chemistry, ligand field theory, and thermodynamics) to explore the larger topic of energy conversion. We will examine how chemistry provides an incredible opportunity when it comes to understanding energy conversion by approaching the problem from the atomic level all the way up to the empirical macroscopic world. Although the path to sustainable energy will be examined primarily through the lens of chemistry, our learning will be placed in the context of political, social economic and environmental goals, which strongly influence future energy production.

Inorganic and Physical Chemistry Laboratory
In this course students will carry out experiments in the field of inorganic and physical chemistry and write journal-style reports based on their results. In the first half of the semester students will conduct a multi-step synthesis and characterization of a Mo-Mo complex with a quadruple bond. Students will learn inert atmosphere synthetic techniques and how to use a glove box. The synthesized Mo-Mo complex will be characterized by UV-Vis, IR, 1H and 31P NMR spectroscopies, and cyclic voltammetry. In the second half of the semester students will conduct two physical chemistry experiments. First students will carry out a kinetic study of the isomerization of the Mo-Mo (alpha to beta or beta to alpha) complex by UV-Vis spectroscopy. Finally, students will obtain the high-resolution IR spectra of acetylene and deuterated acetylene and analyze the rotation-vibration spectra using statistical and quantum mechanics to obtain structural data and interpret the peak intensities. In addition to the laboratory activities, there will be lectures on metal quadruple bonds, principles of UV-Vis , IR, 1H and 31P NMR spectroscopies, cyclic voltammetry, and statistical mechanics. (CHEM 0311, CHEM 0351, and CHEM 0355. CHEM 0355 can be taken concurrently.) 3 hrs. lect. 3 hrs. lab
