Objective
Notes- Stoichiometry
- What is Stoichiometry?
- How can looking at an equation tell you about moles and mass of
the compounds?
- How can mole ratios be determined from a balanced equation?
- What is a mole to mole conversion? How can the mole to mole be
determined?
Notes- Stoichiometry Conversions
- How are mole to mass problems done? How are they different
from a mole to mole conversion?
- How are mass to mass problems done? How many steps are mass
to mass conversions?
- What units must be shown for these types of problems? What
conversion factor must be used for these conversions?
Go over Stoichiometry WS
- Stoichiometry Practice (WS#2)
- What are the three types of stoichiometry?
- What is the difference between a mole to mole, a mole to mass
and a mass to mass?
- How can students logically determine which conversion is
necessary in the problem and can logic help them determine the
conversion factor?
- How many places are necessary in the final answer?
Go over Stoichiometry WS #3
Stoichiometry Quiz
- How can mole ratios be determined for a balanced chemical
equation?
- Can the three types of stoichiometry problems be distinguished
and calculated?
- Can a stoichiometry problem be solved without first writing a
balanced chemical equation?
- What is a hydrocarbon combustion reaction?
Lab #16 Stoichiometry Lab
- What happens when aluminum foil is added to copper (II) chloride?
- What is the balanced chemical equation for this single replacement
reaction?
- What happens to the temperature of the reaction as the reaction
proceeds?
- How can the theoretical yield of the products be calculated from
the starting masses?
A- S’more Activity
- What is stoichiometry and can it be applied to calculate how many
S’mores can be made from a set amount of materials?
- What is a limiting reactant? Can students practice the concept of a
limiting reactant is by making S’mores?

Notes- Limiting Reactant
- What are the steps needed to calculate the limiting reactant?
- Once the limiting reactant is found what other calculations can be
done?
- How can the left over excess reactant be calculated?
- How can excess used during a reaction be determined?
- Why is the balanced equation so important during limiting reactant
problems?
Limit Practice
- How can a limiting reactant be calculated? Where do the
comparison numbers come from when finding which reactant is
limiting?
- Why do students start with the limiting reactant for every other
type of calculation dealing with a limiting problem?
Notes- Percent Yield
- How is percent yield calculated and how is it different from percent
error?
- How can the theoretical be calculated from a basic stoichiometry
and then be plugged into a percent yield problem?
Stoichiometry Review
- What are the three types of stoichiometry and how can they be
calculated?
- What is a limiting reactant and how can it be calculated?
- How can the theoretical yield of a product be calculated once the
limiting is determined?

- How can percent yield be calculated?
- How can a limiting reactant problem be determined without the
problem specifically saying find the limiting reactant?
