Chemistry Stoichiometry test
to determine the limiting reactant in a chemical reaction, one must know the
available amount of each reactant
if you know the mole ratio of a reactant and product in achemical reaction, one can
calculate the mass of the product produced from a know mass of reactant.
mole ratio
each of the four types of reaction stoichiometry problems requires using a...
in most chemical reactions the amount of product obtained is
less than the theoretical yield
a chemical reaction involving the substances A and B stops when B is completely used. B is the
limiting reactant
a balanced chemical equation allows on to determine the...
mole ratio of any two substances in the reaction
a chemist interested in the efficiency of a chemical reaction would calculate the
percentage yield
when the limiting reactant in a chemical reaction is completely used, the
reaction stops
if the percentage yield is equal to 100%, then
the actual yield is equal to the theoretical yield.
actual yield
the measured amount of a product obtained from a chemical reaction.
percentage yield
the ratio f the actual to the theoretical yield, multiplied by 100%.
limiting reactant
the reactant that controls the amount of product formed in a chemical reaction.
reaction stoichiometry
the study of the mass relationships among reactants and products in a chemical reaction
