2. Log #4 – Update
3. Counting Total Atoms in Compounds + Bohr/Lewis Dot Review– Bookshelf – 3 pages 5 sides- Please STAPLE
4. CSI – Web Adventure – Due Now
1. Cover and Table of Contents MUST be done on the Computer (Available tomorrow)
2. Final Exam (Tues & Thur of next week) – ½ page of notes, front side only, done by hand (Available tomorrow)
3. If you haven’t take Test #4 – Please schedule for Thur, Fri or Mon.
1) Count the Atoms of one molecule
2)and then multiplying that by how many molecules you need to build.
Example:
#2: 4 HNO3
H = 1N = 1O = 3
X 4
=5 atoms 20 atoms
Coefficient
1) You will need: Yellow, Red, Green and Black
2)Color molecules according to key
Yellow = Hydrogen
Red = Oxygen
Green = Chlorine
Black = Carbon
1) Build a model of Compound Listed Below
• Managers = CCl4
• Materials Managers= C2H4
• Oral Presenters = CH3OH
• Timer/Designer = HCHO
