1. Stoichiometry

2. Outline Stoichiometry Interpreting Equations Mole Ratio
Limiting and Excess Reagent
Theoretical and Actual Yield
Percent Yield

3. Stoichiometry Calculation of quantities in chemical reactions
How much (mass, volume, moles, etc.) we are working with?
Think of it as the accounting of chemistry

4. Interpreting Equations
Balanced equations can be interpreted in terms of: atoms, molecules, moles, mass, and volume.
Atoms, molecules, and moles easy to work with
Mass and volume are more difficult

5. Mole Ratio
Conversion factor derived from coefficients of a balanced equation in terms of moles.
For example: 2H2 + O2 -> 2H2O has a mole ratio of 2:1:2

6. Limiting and Excess Reagents
Limiting: Reagent that determines the amount of product that can be formed
Excess: Reagent that is not completely used up in a reaction
Sandwiches

7. Theoretical and Actual Yield
Theoretical: Maximum amount of product that could be formed from given amounts
Actual: Amount of product that actually forms when carried out.
Furnace

8. Percent Yield
Ratio of the actual yield to the theoretical yield expressed as a percent.
If I was supposed to get 10 grams and I only got 8 grams, my percent yield would be 80%
