Counting Total Atoms in Compounds
Transcript of Counting Total Atoms in Compounds
You Will Need:
• Pencil, Colored Pencils, Periodic Table (textbook)
• Log #5 – Bookshelf
• Counting Total Atoms in Compounds – Bookshelf – 2 pages 4 sides
• Cover and Table of Contents MUST be done on the Computer (Computer Cart here tomorrow)
• Test #4 – ½ page of notes, front side only, done by hand
• Count the Atoms of one molecule
• and then multiplying that by how many molecules you need to build.
Example:
#2: 4 HNO3
H = N = O =
X 4 =5 atoms 20 atoms
113
