About the content
This is an introductory course for students with limited background in chemistry; basic concepts involved in chemical reactions, stoichiometry, the periodic table, periodic trends, nomenclature, and chemical problem solving will be emphasized with the goal of preparing students for further study in chemistry as needed for many science, health, and policy professions..
- Week 1 - Introduction
Over the seven weeks of Introduction to Chemistry: Reactions and Ratios, you will be able to progress from a most basic knowledge of matter and energy to solving interesting real world chemical reaction stoichiometry problems. Each lesson in the course intr...
- Week 2 - Matter and Energy
If you are interested in significant figures in more detail, here are some good videos to follow on Khan Academy.
- Week 3 - Compounds
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 - Chemical Composition and Reactions
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...
- Week 5 - Solutions and Solubility Rules
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...
- Week 6 - Acid-base and Redox Reactions
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!
Week 6 for Introduction to Chemistr...
- Week 7 - Final Exam
Congratulations on making through to the final week of the course! It was not an easy journey for the past six weeks with dozens of videos, exercises, problem sets, and forum discussions. Kudos to the many of you who completed the honors lessons on top of the ...
