Module 1 Overview & Instructions
Foreword
All the material for this first week of the course *should be* review from CHEM 1210, General Chemistry I. If you find you need more of a review than the material in the Stuff to Read, Watch, and Think About section, check out the (completely optional) videos in the Additional Resources section at the bottom of the page.
Questions and Answers
Whatever you're struggling with this week, somebody else in our section probably is struggling with it, too. Post your question on the Module 1 Q&A Board.
If you know the answer to someone's question, post it. It's almost a certainty that more people in our section than just the person who posted the question want to know the answer.
Learning Outcomes/Objectives
By the conclusion of this learning module, you should be able to:
- recognize molecular and nonmolecular substances.
- differentiate between intramolecular and intermolecular forces.
- understand temperature as a measure of average kinetic energy.
- use q = mc
ΔT to relate heat flow and temperature change.
- understand constant-temperature heat flow during phase changes.
- understand heating and cooling curves.
- analyze a mixed-phase system.
- understand the concept of dynamic equilibrium as it relates to vapor pressure.
- use the Clausius-Clapeyron equation to calculate vapor pressure as a function of temperature.
- understand the concept of boiling point and its relationships with vapor pressure and applied pressure.
- interpret phase diagrams.
- understand the differences between and relative magnitudes of dispersion forces, hydrogen bonding, and dipole-dipole forces.
- recognize substances that exhibit hydrogen bonding.
- rank substances according to their relative freezing or boiling points.
- understand the concept of unit cells in describing solid-state structure.
- understand the bases for the high melting points of ionic compounds and covalent network solids.
- understand the relationship between structure and solubility for molecular compounds.
- calculate ion concentrations for solutions of ionic compounds.
