Balancing Equations, Using Pictures (Genova, 6:51)
-Visual way to balance equations. Not great for very complex equations. A good place to start, but not necessary if you understand the list method.
Balancing Equations, Using a List (Genova, 8:02)
-Method to balance equations that works well for simple or complex equations. If this does not make sense, try the picture method until you are more comfortable with the process.
Balancing Equations, Trick (Genova, 4:30)
-A trick to help you with some very difficult equations.
Types of Reactions (Genova, 7:23)
-How to classify a reaction as synthesis, decomposition, single replacement, double replacement, or combustion. For some reason, MCAS loves these. Fortunately, you can learn to get them all correct after watching this video.
Predicting Products (Synthesis, Decomposition, Combustion) (Genova, 3:24)
-How to predict what substances will be made in these three types of reactions.
Predicting Products (Single and Double Replacement) (Genova, 3:24)
-How to predict what substances will be made in these two types of reactions.
Converting Between Moles, Mass, & Particles (van Geel, 12:16)
-Several examples of these types of problems, which form the basis for most chemistry calculations. EXTREMELY IMPORTANT to understand.
NOTE: THERE IS AN ERROR ON THIS VIDEO. I AM WORKING TO FIX IT. Whenever he writes 6.02 x 10^24, it SHOULD BE 6.02 x 10^23.
Percent Composition (van Geel, 5:29)
-How to determine the % makeup of each atom from a chemical formula
Empirical Formulas (van Geel, 8:40)
-Given the percent composition, how to find a substance's empirical formula (the most "reduced" formula)
Molecular Formulas (van Geel, 4:57)
-How to find a substance's molecular formula, knowing its empirical formula and its approximate molar mass.
Percent of Water in a Hydrate (Genova, 4:34)
-Calculate the % of water in a hydrate from its formula. Determine how a hydrate's mass will change when heated.
Finding the Formula of a Hydrate (Genova, 4:20)
-Determine the number of water molecules in a hydrate based on laboratory data
