
I will be able to conduct an inquiry to
determine the actual yield, theoretical yield,
and percentage yield of the products of a
chemical reaction (e.g. a chemical reaction
between aluminum and copper(II) chloride,
assess the effectiveness of the procedure, and
suggest sources of experimental error.
I will be able to use qualitative observations of
a chemical reaction to identify the chemical
changes, presence of limiting reagents, and the
products occurring in a chemical reaction.

determine the limiting reagent when given the
amounts of reactants
predict the amount of product formed in a reaction
based on the amount of the limiting reagent
determine the limiting reagent when given the
masses of reactants
predict the mass of product formed in a reaction
given the mass of the limiting reagent
identify the theoretical yield as the quantity of
product as predicted by the stoichiometry of the
chemical equation
identify the actual yield of a reaction as the actual
quantity of product collected
compare the actual yield with the theoretical yield
and suggest possible causes for any differences
between them
calculate the percentage yield of a reaction given the
amounts or the masses of reactants and the actual
yield of the desired product
identify a limiting reagent based on observations
calculate theoretical yield and percentage yield from
experimental data
conduct an experiment to quantitatively collect the
product formed
