Stoichiometry Test Study Guide

Ace your homework & exams now with Quizwiz!

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
