STAGE I – DESIRED RESULTS
LESSON TOPIC: Stoichiometry
BIG IDEAS: (Content standards, assessment anchors, eligible content) objectives, and skill focus)
Chemical reactions are predictable.
ESSENTIAL QUESTIONS:
How do stoichiometric ratios relate reactants to products in a chemical reaction?
UNDERSTANDING GOALS (CONCEPTS): Students will understand:
·  A chemical reaction will proceed until equilibrium is reached or until a limiting reactant is exhausted.
·  According to the law of conservation of matter, the mass of the products in a chemical reaction is equal to the mass of the reactants.
·  The amounts of reactants and products involved in a chemical reaction can be predicted using mole relationships.
·  Dimensional analysis is a mathematical technique that can be used to express stoichiometric relationships.

VOCABULARY:

stoichiometry, formula mass, balancing equations, limiting/excess reagents, actual/percent/theoretical yield

STUDENT OBJECTIVES (COMPETENCIES/OUTCOMES): Students will be able to

·  determine formula masses and percent composition of a substance.
·  convert between mass, moles, and number of units (e.g., molecules, atoms, ions) for a formula and its subunits.
·  determine empirical and molecular formulas using composition data (mass, percent composition, elemental analysis).
·  write, interpret, and balance (by inspection) chemical equations.
·  calculate amounts (mass, moles, molecules/formulas units) of reactants and products involved in a chemical reaction.
·  use limiting reagent concepts in calculations involving chemical equations.
·  use actual yields, theoretical yields, and percent yields in calculations involving chemical equations.
·  use the terminology of solutions.
·  convert between different concentration units.
·  perform dilution calculations.
·  use solution volumes and concentrations in calculations involving chemical equations.
