stoichiometry Flashcards
the starting materials in a chemical reaction
reactants
a conversion factor derived from the coefficients of a balanced chemical equation interpretation in terms of moles
mole ratio
the maximum amount of product that could be formed in a reaction
theoretical yield
the amount of a substance that contains 6.02 x 10^23 representative particles of that substance
mole
the substance completely used up in a chemical reaction
limiting reagent
the ratio of how much product is produced compared to how much is expected, expressed as a percentage
percent yield
the calculations of quantities in a chemical reaction
stoichiometry
the actual amount of product in a chemical reaction
actual yield
the substance left over after a reaction takes place
excess reagent
a stoichiometric computation in which the mass of products is determined from the given mass of reactants
mass- mass calculation
the _____ in a balanced chemical equation also reveal the mole ratios of the substances involved
