General Chemistry in Videos
This is a series of lectures in videos covering topics in General Chemistry. They are conducted by Dr. Chuck Wight who teaches chemistry at the University of Utah.
Reaction Yields
This lecture discusses how to compute the yield of a chemical reaction by using the molar masses of reactants and products.
This lecture talks about the ideal gas law, PV=nRT, the kinetic theory of gases, and a little bit about the properties of real (non-ideal) gases.
This lecture introduces several different types of energy, including heat and enthalpy. We discuss the First Law of Thermodynamics and how to calculate the enthalpy change for a chemical reaction.
Try out our new and fun Fraction Concoction Game.
Add and subtract fractions to make exciting fraction concoctions following a recipe. There are four levels of difficulty: Easy, medium, hard and insane. Practice the basics of fraction addition and subtraction or challenge yourself with the insane level.
