Stoichiometry Test Study Guide
What branch of chemistry deals with the mass relationships of elements in compounds and the mass relationships among reactants and products in chemical reactants
Stoichiometry
what is the measured amount of product obtained from a chemical reaction
actual yield
to determine the limiting reactant in a chemical reaction one must know the
available amount of each reactant
if one knows the mole ratio of a reactant and product in a chemical reaction one can
calculate the mass of the product produced from a known mass of reactant
to balance a chemical equation it may be necessary to adjust the
coefficients
What is the study of mass relationships of elements in compounds
composition stoichiometry
a determination of the masses and number of moles to sulfur and oxygen in the compound sulfur dioxide would be studied in
composition stoichiometry
the units of molar mass are
g/mol
in most chemical reactions the amount of product obtained is
less than the theoretical yield
a chemical reaction involving substances A and B stops when B is completely used B is the
limiting reactant
after calculating the amount of reactant B required to completely react with A then comparing that amount with the amount of B available one can determine the
limiting reactant
which reactant controls the amount of product formed in a chemical reaction
limiting reactant
each of the four types of reaction stoichiometry problems require using a
mole ratio
if one knows the mass and molar mass of reactant A and the molar mass of product D in a chemical reaction one can determine the mass of product D produced by using the
mole ratio of D to A in the chemical equation
a balanced chemical equation allows one 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
what is the ratio of actual yield to theoretical yield multiplied by 100%
percentage yield
What si the study of the mass relationshios among reactants and products in a chemical reaction
reaction stoichiometry
when a limiting reactant in a chemical equation is completely used the
reaction stops
the coefficient in a chemical equation represent the
relative numbers of moles of reactants and products
a chemical equation is balanced when the
same number of each kind of atom appears in the reactants and in the products
in what kind of reaction do two or more substances combine to form a new compound
synthesis reaction
if the percentage yield is equal to 100% then
the actual yield is equal to the theoretical yield
which of the following would not be studied in the branch of chemistry called stoichiometry
the amount of energy required to break the ionic bonds in calcium flouride
which of the following would be investigated in reaction stoichiometry
the mass of potassium required to produce a known mass of potassium chloride
to determine the limitig reaction in a chemical reaction involving known masses of A and B one could first calculate
the number of moles of B and the number of moles of A
what is the maximum amount of product obtained in a chemical reaction
theoretical yield
