DATE OF LAST REVISION: Fall 2022
The first in a series of two courses designed to cover general chemistry including measurement, atoms, molecules and ions, stoichiometry, chemical reactions, solids, liquids, and gases, thermochemistry, atomic structure, and molecular bonding. One year of high school chemistry or one semester of college introductory chemistry is recommended. Includes lab.
MAJOR COURSE LEARNING OBJECTIVES: Upon successful completion of this course the student will be expected to:1. Explain and use measurement techniques including correct unit conversions, dimensional analysis, and significant figures. 2. List the parts of an atom, classify matter, name those substances, and discuss their place on the periodic table. 3. Apply the concepts of stoichiometry including molar mass, percent composition, balancing equations, and limiting reagents. 4. Categorize chemical reactions and predict the products of common chemical reactions 5. Describe the kinetic molecular theory of gases and apply the knowledge using accepted gas laws. 6. Explain the basics of thermochemistry including enthalpy, calorimetry, Hess’s law, and standard enthalpies of formation and solve problems using these concepts 7. Interpret the quantum mechanical model of the atom including quantum numbers, orbital shapes, orbital energies, electron spin, and the Pauli Principle as well as the periodicity, which rises from this model. 8. Illustrate the basic concepts of ionic bonding and polar covalent bonding and their relationship to electron configuration, as related to the concepts of electronegativity, bond polarity, and dipole moment. 9. Compare and use the VSEPR model, the hybridization model, and the molecular orbital model for covalent bonding. 10. Identify intermolecular forces and relate how they affect solution formation. 11. Write and interpret nuclear equations and describe the nuclear stability of an isotope.
