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
