Learning Intentions
You can identify what a limiting reagent is in a chemical reaction when you are given amounts for more than one reactant.
You can use stoichiometry to determine what the limiting reagent is in a chemical reaction when you are given amounts for more than one reactant.
You can use stoichiometry to determine theoretical yield of one of the products for a limiting reagent problem and then use it to determine percent yield for a chemical reaction..
Content Standards being covered:
Student can create mathematical representations of chemical
reactions and use them to make calculations about products and reactants.
156. Theoretical yield is the calculated or anticipated amount of product
expected at the end of a chemical reaction most often measured in grams
157. The actual yield, or experimental yield is the amount
of product produced in grams at the end of the real experiment
158. The percent yield of a reaction describes the amount of products created
(actual yield/ theoretical yield X 100)
174. In a chemical reaction, the reactant that runs out first is called the
limiting reactant (reagent) and the other reactant is in excess
Habits of Mind/Life skills being covered:
Applying past knowledge to current situations
