In this week's videos and exercises (aka quizzes), we will learn how to name compounds, calculate formula masses, convert between grams and moles, examine periodic trends, and more!

I hope you enjoyed the last two weeks of learning chemistry. Great wo...

Week 4 for Introduction to Chemistry: Reactions and Ratios is about to begin! This week will be filled with introductions to chemical compositions, chemical reaction terminology, and reaction calculations.

If any of the following questions interest yo...

In the past five weeks of the course, we have learned concepts, rules, and skills, including but not limited to: the definitions of atoms, elements, molecules, and compounds; energy changes; Coulomb’s Law, molecular stoichiometry; atomic structures; periodi...

We are almost at the end of our course! I hope this has been a rewarding experience for you because I know that the course is not an easy one and it is relatively long. So kudos to everyone who has made it this far!
