Course Description
Explores and applies principles presented in CH 221Z to the study of the solid, liquid, and gaseous states of matter. Principles of stoichiometry, thermochemistry, kinetics, and foundational equilibrium are explored and applied to the study of aqueous and gas-phase chemical reactions. CH 222Z is a lecture course; CH 228Z is the laboratory component. Must be coregistered with CH 228Z. To satisfy the lab science requirement, both CH 222Z and CH 228Z must be completed with a grade of C or P or better. The PCC Chemistry Department strongly recommends that students take CH 221Z/CH 227Z, CH 222Z/CH 228Z and CH 223Z/CH 229Z in consecutive terms. Audit available.
Intended Outcomes for the course
Upon successful completion of he course, students should be able to:
- Apply stoichiometry to a variety of problems involving reactions, gases, liquids, solutions, thermochemistry, kinetics, and equilibrium expressions.
- Apply kinetic molecular theory and gas laws to predict the behavior of gases at various conditions.
- Identify types of intermolecular forces and apply them to physical properties of solids, liquids, and solutions.
- Describe solution concepts and factors affecting solution properties.
- Determine the effects of different factors on chemical reaction rates and examine the role of catalysis in modifying these rates.
- Apply concepts of thermochemistry to explain thermal energy transfer and the energy changes that accompany chemical and physical changes.
- Identify and apply appropriate equations related to gas laws, solutions, colligative properties, thermochemistry, kinetics, and equilibrium expressions.
Quantitative Reasoning
Students completing an associate degree at Portland Community College will be able to analyze questions or problems that impact the community and/or environment using quantitative information.
