JUNIOR CHEMISTRY

The Mole 1 - introduces the mole concept; Avogadro's number The Mole 2 - converts atoms to moles; performs molar mass calculation The Mole 3 - converts mass to moles; mass to atoms Stoichiometry 1 - gives the answer to: How many moles of silver chloride forms when 2.6 mol of KCl reacts with excess silver nitrate in solution. Stoichiometry 2 - takes you through a stoichiometry problem that involves finding a mass of product where a reactant mass is known Stoichiometry 3 - performs a limiting reagent question AP CHEMISTRY

Stoichiometry 1 - teaches the atomic weight (molar mass) calculation and mass percent Stoichiometry 2 - does a question that converts % composition by mass into an empirical formula Stoichiometry 3 - calculates the water of hydration (crystallization) of an ionic compound Georgia Public Broadcasting Video Lectures

This public station has an entire high school level chemistry course online. This is not an honors-level course like ours but the videos are useful nonetheless. Each video is a 30 minute lecture on a very specific topic.

If you want to try their note-taking system for the lecture, print out the “Note Taking Guide” on the page.

Chapter 3: Chemical Reactions and Earth's Composition

There is a diagnostic quiz (some of the questions cover topics that not relevant for us). The ChemTours (basically multi-media tutorials) are excellent and I highly recommend them. You should look at the ones on: Avogadro’s Number Percent Composition Limiting Reactant

Education Portal – Chemistry 101: General Chemistry

Avogadro's Number: Using the Mole to Count Atoms Mole-to-Mole Ratios and Calculations of a Chemical Equation Mass-to-Mass Stoichiometric Calculations Stoichiometry: Calculating Relative Quantities in a Gas or Solution Limiting Reactants & Calculating Excess Reactants Calculating Reaction Yield and Percentage Yield from a Limiting Reactant Calculating Percent Composition and Determining Empirical Formulas Hydrates: Determining the Chemical Formula From Empirical Data ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Hill & Petrucci; General Chemistry (Companion Site for College Chemistry Text) Chapter 3: Stoichiometry: Chemical Calculations e-Media activities (list)
