Pep Rally Day 6
AP: Over the weekend, I will grade the test from today. Check out these tutorials to give yourself a better understanding of Kinetics, which we should be able to finish next week:
Kinetics Tutorial
Kinetics Videos and Animations
Regents: today, we covered the remaining types of intermolecular attractions and how to recognize which molecules have which attractions. Overall, you now know ion-dipole, hydrogen "bonding", dipole-dipole, and induced dipole attractions. Check out the tutorial (from the class website) regarding those attractions:

Monday, we have a lab exam, which will be the final 100 points for the quarter. The objectives for that exam are posted on the website. Make SURE that you know everything about them intuitively, by Monday. If you have a question about a particular objective, just email me before Sunday afternoon/early evening. Don't forget about the GRADED hw assignment that you must hand in by Monday, if you have not already done so: Orange Review Book Topic 6 Bonding vocabulary word definitions, complete and thorough. Those points will help your second quarter grade.

I intend to finish the Bonding Unit by next Wednesday after which we start the Math of Chemistry unit! For approximately the next 6 weeks, the course will mostly involve relationships/scientific laws/equations that involve division, multiplication, and ratios. All formulas will have to be repeatedly practiced and applied until you know them by heart because you will not be given any equations/formulas on any test.
FAIR WARNING: In the equations and calculations, all measurements and constants that have physical units (ex: grams or moles or liters) must be written WITH those units or you will not receive ANY credit for your answers. Proper cancellation of units in calculations is also required. Do not EVER forget those two requirements or your third quarter will be a disaster for sure. Do not ever practice taking shortcuts without units or you will be training yourself to fail.
On the other hand, you won't be asked to "explain" an equation; you will just have to know HOW and WHEN to apply the equation. We have been through two quarters so, even if you still have not yet been able to write/draw a good explanation (I don't know how that is possible by now, though), you, at least, now know what is expected when you are asked to explain something.
In the past, the majority of students start to achieve higher grades in the third quarter because they take the Math of Chem section very seriously and practice each problem type until they know it inside out. The problems are very direct and do not have too much variety; each can be mastered consecutively and even combined in a several step problem.
Study hard for Monday.
