Stoichiometry Test Review
the amount of chemical that you actually make
the amount of product which should be made in a chemical reaction
the cemical that determines how far the chemical reaction will go before the chemical in question gets used up, causing the reaction to stop
The actual yield divided by the theoretical yield times 100
the reactant that remains when a reaction stops when the limiting reactant is completely consumed
is conserved in every oridnary chemical reaction
the______is the quantity that can be used in the same way as moles when interpreting blanaced chemical equations
number of molecules
the _____is conserved only in reactions where te temperature is constant and the number of moles of gasous reactants is the same as that of gasous products
the calculation of quantitites in chmical equationstis called
what four things are conserved?
mass, moles, molecules, and volume
in every chemical reaction, ___and ____ are conserved
in a chemical reaction, the mass of the products is_____to the mass of the reactants
which type of stoichimetric calculation does not requre the use of the molar mass?
volume to volume
when two substances react to form products, the reactnat which is used up is called the
when an equation is used to calculate the amount of product that will form during a reaction, then the value obtained is called the
the amoun of product obtained is determine by the limiting reagent
the react that has teh smallest given mass is the limiting reagent
a blanced equation is necessary to determine which reactant is the limiting reagent
some of teh excess reagent is left over after the reaction is complete
list thee reasons why the actual yield would be less than theoretical yield
impure reactants present, competing side reactions, and loss of product during purification
