So you’ve determined a percent composition from a compound’s formula. Big deal. Now it’d be something if you could determine an empirical formula from...

These lessons will provide most of what is covered in a typical introductory chemistry class. Bring your enthusiasm and let’s learn some chemistry!
Once you have a molar mass, it is not a big stretch to breakdown the mass percent of each constituent element. Intrigued? Take a look.
Determining the molar mass of an entire compound is only slightly tougher than doing the same for a single atom. The real work comes in when you want to properly show...
There are few concepts more important in introductory chemistry than the mole. Really, it’s nothing more than a glorified ‘Chemist’s Dozen’, but...
There is a lot more a chemistry student can do with numbers beside balance equations. A great chemistry student must be comfortable converting between different mass...
People love labeling stuff. As scientists go, chemists probably label less than most (don’t get me started on biologists…) but every now and then they get...
Oxidation states are the work-around chemists made so every compound can be considered in terms of actual or theoretical charge. Realistic? Not really, but very useful...
A brief introduction to a deep and rich vein of chemistry content. Oxidation-reduction reactions are the final driving force we will discuss in this series. Learn how...
Arrhenius figured out that acids can be thought of as H+ donors and bases could be thought of as OH- donors. What happens when you bring these two powerhouses together...
In this video, we’ll take another look at precipitation reactions, specifically the combination of lead (II) nitrate and sodium iodide. Practice makes perfect, so...
