***UPDATE***
The FINAL in this course will be administered after the break (11:05-1:55) on Wed., July 12th.
NO HOMEWORK WILL BE ACCEPTED AFTER WEDNESDAY, ONLY CLASSWORK
Mr.Hatfield's 2nd-session Chemistry students took their third test today. A class roster of 44 has now been reduced to 23 actively attending.
The good news is that some have raised their output in the course, and now have a passing grade. The concern is that still too many students are failing to complete work outside of class, and thus are in danger of not passing the course. With that in mind, here are more resources to help students 'up their game' .
FIRST: Students received notes on reaction rates and equilibrium constants in class. A copy of the Notes can be found HERE:
NEXT: Students will be using a third Study Guide to complete the rest of their Notes, based on material from Chapter 19. They can download a copy of the Power Point containing those Notes HERE:
FINALLY: Students were given a worksheet based on the following video, shown in class. This worksheet is due tomorrow!
You can view the video, below:
It demonstrates the centrality of water to most acid-base chemistry, and explains how to calculate equilibrium constants for acids (Ka) and bases (Kb), and how to express those as pKa's or pKb's:
