CH.4 b - Stoichiometry
The student will investigate and understand that chemical quantities are based on molar relationships. Key concepts include:
b) stoichiometric relationships.
Bloom's Levels: Analyze; Understand
- Balanced chemical equations represent the ratios of substances that react with one another to produce different substances.
- I can determine how many cookies I can make from a set of ingredients.
UNDERSTANDING THE STANDARD
Stoichiometry involves quantitative relationships. Stoichiometric relationships are based on mole quantities in a balanced equation.
Total grams of reactant(s) = total grams of product(s).
In order to meet this standard, it is expected that students will
b) perform stoichiometric calculations involving the following relationships:
- mass-particle; and
identify the limiting reactant (reagent) in a reaction.
calculate percent yield of a reaction.
