Chemistry Chapter 12

The amount of product formed when a reaction is carried out in a laboratory.

• actual yield

• percent yield

• theoretical yield

• master yield

The ratio of the actual yield to the theoretical yield.

• actual yield

• percent yield

• theoretical yield

• mass

the reactant that is not completely used up in a reaction

• theoretical yield

• mass

• excess reagent

• limiting reagent

This quantity can always be used int he same way as moles when interpreting balanced equations.

• volume

• number of molecules

• actual yield

• mass

The maximum amount of product that could be formed from given amounts of reactants.

• theoretical yield

• actual yield

• volume

• percent yield

The reactant that determines the amount of product that can be formed in a reaction

• excess reagent

• limiting reagent

• number of molecules

• volume

This is conserved in every ordinary chemical reaction.

• volume

• limiting reagent

• actual yield

• mass

This is conserved only in reactions where the temperature is constant and the number of moles of gaseous reactants is the same as that of the gaseous products

• mass

• volume

• percent yield

• excess reagent

• 3.5 moles HCl

• 1.45 molecules FeCl₃

• 5 g FeCl₃

• 3.76 g FeCl₃

• 1.45g FeCl₃
