This General Chemistry course will cover fundamental chemical principles broadly applicable in Chemistry, Biochemistry, Medical Science, Materials Science, and various fields of Engineering. In one semester, we will focus on a general introduction to chemical principles including stoichiometry, basic quantum mechanical principles with an emphasis on electronic structures of atoms and chemical bonding, chemical kinetics, equilibrium phenomena, and laws of thermodynamics. The goal is to straightforwardly introduce notions that advance beyond High-school Chemistry and to provide the foundations for a systematic understanding of the various disciplines in Chemistry for serious-minded students.
