Stoichometry
the calculation of quantities in chemical equations (form of bookeeping)
Coefficient
Coefficient of a balanced equation give you the relative numbers of moles of reactants and products in the chemical reaction
Mass and atoms
are conserved in every chemical reaction
STP
Mass-volume, volume-volume, and particle-mass
Limiting reagent
limits or determines the amount of product that can be formed in a reaction
Excess reagent
the quantity of a excess reagent is more than enough to react with a limiting reagent.
Theoretical yield
When an equation is used to calculate the amount of product that will form during a reaction, a value for theoretical yield is formed.
Actual yield
In contrast the amount of product that forms when the reaction is carried out in the laboratory is called the actual yield.
Percent Yield
the ratio of the actual yield to the theoretical yield expressed as a percentage.
