First off, sorry for the delay as I'm finally writing the blog on Wednesday morning and we're half way through the week.
As usual, subject to change and adjustments:
Chem-I:
Monday and Tuesday (already past): We went over half-test on ionic compounds. Reminder that a re-take will be offered through Friday, 2:15 PM (to a max of 80%) for those who "struggled". Make sure you have reviewed and corrected your mistakes before attempting the retake. There was no HW due for tuesday.
Also on Monday and Tuesday we started covering Molecular Compounds: Single, double and triple bonds; diatomic molecules; VSEPR Theory and Coordinate Covalent bonding. There are two things due for Wed/Thurs block day: 1. Complete the worksheet on drawing out the 12 covalently bonded molecules, and 2. Pre-Lab questions on Lab titled "Composition of Hydrates".
Wed/Thursday: Worksheet and pre-lab are due. We will be going over worksheet and adding a couple of more molecules to our list. I will be introducing the concept of polarity with polar and non-polar bonds and polar, non-polar moleccules and assigning pos and neg dipoles (based on electronegativity). We will then do the lab on Comp of Hydrates. DUE FOR FRIDAY: from the "Drawing Molecular Compounds" worksheet that was due today, you will now determine polarity (both bond polarity and molecule polarity) for compounds #3 though 10 and the two "extras" (we'll call them 13 and 14) that we'll add today.
Friday: We will review polarity and then there will be a quiz on all the material from this week: covalent bonds, diatomics, VSEPR, coordinate covalent bonding and polarity. For those students who will not be in class on Friday due to UNH field trip, be prepared to make up the quiz on Monday (probably during class time).
NOTE THAT I PLAN ON GIVING A UNIT TEST NEXT WEEK, probably on Friday.
