Honors Chemistry Stoichiometry
Terms in this set (15)
the amount of product that forms when a reaction is carried out in the laboratory
a reagent present in a quantity that is more than sufficient to react with a limiting reagent; any reactant that remains after the limiting reagent is used up in a chemical reaction
any reagent that is used up first in a chemical reaction; it determines the amount of product that can be formed in the reaction
the ration of the actual yield to the theoretical yield for a chemical reaction expressed as a percentage; a measure of the efficiency of a reaction
that portion of chemistry dealing with numerical relationships in chemical reaction; the calculation of quantities of substances involved in chemical equations
the amount of product that could form during a reaction calculated from a balanced chemical equation; it represents the maximum amount of product that could be formed from a given amount of reactant
moles, mass, volume, and number of particles
What kind of information can you find from a chemical equation?
size of particles
What kind of information can you not find from a chemical equation?
law of conservation of mass
A balanced chemical equation must obey what law?
balanced chemical equation
What is essential for all calculations involving amounts of reactants and products?
the coefficients from a balanced chemical equation are used to write conversion factors
What does a sample need to be measured in so that the molar mass can be used to convert the mass to moles?
convert moles to moles, use mole ratio and then convert moles to mass
What are the steps needed to solve a mass-mass stoichiometry problem?
What is the given quantity first converted to in any stoichiometric calculations?
impure reactants, completing side reactions, loss of product during filtration and careless measuring
Describe four factors that may cause percent yields to be less than 100%
