How do chemists calculate how much product they can make, or how much of each reactant to combine in chemical reactions?

Find out in chapter 4!

This module explores:

balancing chemical equations
Using the mole:mole ratio in a chemical reaction like a baking recipe
Calculating % yield
Determining the limiting reactant in a chemical reaction

NOTE: If you have an earlier edition of the text (3 or 4), chapter 4 and 5 of the new editions were originally 1 chapter (ch 4). If you have an older book, your chapter 4 is really long, and all of the other chapters are one number less that the 5th edition.

Reading Guides:

There is a reading guide for chapter 4 of course! If you have a 3rd or 4th edition, we're just doing the 1^st half of your chapter 4.

For you to do this week:

Keep memorizing the ion/element list (online version). You should add in the rest of the ions.
- The goal is to become so familiar with all of the ions/elements that you don't need the sheet for the 2nd half of the semester)
I spend a gazzillion hours making lecture videos. I hope you're watching! And using the Printable Lecture Notes!
Prepare for Exam 1 (Wednesday 2-23) covering chapters 1-4 (only through stoichiometry/LR). Writing chemical formulas will be on the exam.

Week 4 notes

Elements and ions to know Practice the list!
Tuesday 2-9 In class worksheet intro to stoichiometry Key
Practice naming compounds and writing formulas One Two
Practice balancing chemical reaction equations (plus writing formulas from names-priceless!)
Practice quiz chapter 3 and key
MC due Monday, but don't wait until then. You'll want to be studying for the exam.
