Hon Chemistry 2-28-18 Resonance & Polyatomic Ions

HON CHEMISTRY: Wow! Lewis structures, multiple bonds, and now resonance, and now polyatomic ions! That’s a lot you’ve conquered in the last couple of days!

Here’s some good advice – don’t take shortcuts. Learn the proper steps on the easier molecules, and you’ll be able to do the hard ones. And if it’s still all Greek to you, don’t worry! Keep practicing and you’ll get it, I promise!! Don’t forget to count electrons and don’t forget CONS!

Physics 2-27-18 Bernoulli

PHYSICS: Were you amazed at the effect of change in surface area on the velocity of water, and especially the pressure of water, flowing through a tube? Thaaaaat explains how a calm ride on a lazy river can turn crazy in just a few seconds!

I dug up two old lessons from Bernoulli and posted them below – First, Bernoulli Part 1. We mainly concentrated on qualitative applications of Bernoulli’s Principle with some practical applications. (Ignore all the discussion about the syllabus!!) The second covers more of the conceptual stuff with a beginning look at the problems.

Speaking of syllabus, UPDATE: Pg. 289: 17 – 21 and Bernoulli Worksheet DUE FRIDAY
