Quiz Information:
All Gone!!! Finished, ended, no more!!!!
Please go to the previous page and check the Final Exam Information link.
Remember the Final is on Tuesday May 4th at 10:00 a.m.
This link will have a list of information about the upcoming quiz. Quizzes are typically 5-6 questions of various types (multiple choice, short calculation, short essay, etc.). Each quiz is worth 25 points each. Quizzes cover the information from the previous quiz/exam and are given at the last 20 minutes of the class period.
This information page will be updated Wednesday after class when the material covered for the week is known. This page may be updated earlier in the week to reflect my thoughts on which topics are "fair game" after each lecture is complete.
Helpful hint, I will try to select some of the homework problems for the quiz.
Quiz #11 Thursday April 29th LAST ONE ....WOO HOO!!!!! (Remember the Final is Tuesday May 4th @ 10:00 pm)
------------
While each week's quiz will be over that material presented since the cut-off for the last event, some skills learned in the previous weeks may be used as part of the solution to the current week's quiz.
The 11th quiz will start where the material cut off for last exam. That is, Chapter 11 AND 12 are on this quiz.
CHAPTER 11 - INTERMOLECULAR FORCES AND LIQUIDS AND SOLIDS
Phases
Intermolecular Forces
Dipole-dipole Forces
Ion-dipole Forces
London Dispersion Forces (or Dispersion or van der Waal forces) - Very Weak but Go "Up" with Atomic/molecular Weight
Hydrogen Bond - H Bonded to N O F
"Like Dissolves Like"
Use Molecular Forces to Predict about Melting and Boiling Points
Vaporization
Heat of Vaporization
Vapor Pressure
Vapor Pressure Vs. Temperature
Boiling Point a Function of Applied Pressure
CHAPTER 12 - PHYSICAL PROPERTIES OF SOLUTIONS
Units of Concentration
Molality
Mole Fraction
Molarity
Colligative Properties
Vapor Pressure Lowering
Boiling Point Elevation change in T = kb*molality
Freezing Point Depression change in T = kf*molality
Osmotic Pressure Pressure = Pi = difference in Molarity * R * T
