Modern applications of chemistry in context of larger scientific theme, e.g. in biology, materials science, or environmental chemistry. Revisits core concepts from Chemistry 101DL or 110DL, incorporating additional topics including intermolecular interactions, phases of matter, solutions, quantitative treatment of aqueous equilibria, electron transfer reactions, and inorganic and coordination chemistry. Discussion illustrates both qualitative and quantitative approaches to modern problems in biological, materials, and environmental chemistry. Recommended prerequisite: Chemistry 101DL or 110DL.
