CHEM 1523

Principles of Chemistry

3.0 Credits


This course is the second half of first year chemistry theory designed for students with a strong background in Chemistry. Course topics include gas laws, equilibrium, redox reactions, electrochemistry, thermochemistry, entropy and free energy.

NOTE: This course provides the equivalent of the second half of a first-year university chemistry course when taken with its accompanying laboratory course, CHEM 1525. In order to complete the equivalent of the entire first year (6 credits) of university-level chemistry students need to complete CHEM 1503, 1523, 1505 and 1525 or CHEM 1500 and CHEM 1520.

NOTE: You may be required to take CHEM 1525 the lab component in order to receive transfer credit.

Delivery Methods

Online, self-paced.

Recommended Requisites

CHEM 1500, CHEM 1503, CHEM 1505, with a score of C- minimum and Chemistry 12, with a a score of B or better.

Note: If you enroll in CHEM 1523, it is strongly recommended that you have completed CHEM 12 in order to be successful.


CHEM 1520


By the end of this course, students should be able to:

  • Describe the properties of gases and do gas law calculations.
  • Calculate order, rates, half-life, and reaction rate constants from kinetic data
  • Explain the equilibrium state and the effects of an applied stress on an equilibrium.
  • Do a variety of gaseos and ionic solution/solid equilibrium calculations.
  • Explain the concepts involved in the theory of acids and bases.
  • Calculate the pH of solutions of acids, bases, salts, buffers, and polyprotic acids.
  • Do thermodynamic calculations.
  • Explain the concept of entropy and its contribution to spontaneity in Gibbs free energy.
  • Balance redox equations.
  • Describe electrolytic cells and do calculations involving Faraday's Laws.
  • Calculate standard and non-standard cell emf's from standard reduction potentials.
