What is Stochiometry?
Stochiometry is the relationships between the quantities of reactants and products in a chemical reaction. It is mased on the law of conservation of mass, ie. the total mass of reactants must equal the total mass of products. This means that the amount of product can be calculated from the amount of reactant, and vice versa.
Reaction Stochiometry
The quantitative relationships among substances in a chemical reaction
Composition Stochiometry
The use of ratios to determine quantities in a reaction described by a balanced equation
Gas Stochiometry
The study of stochiometry reactions involving only gases with a known temperature, pressure and volume
Stochiometric Amount
The optimum amount of a reagent in a reaction, where all the reagent is consumed with no excess or deficiency.
Stochiometric Number
The precise ratio of reactants required to complete a reaction with no excess or deficiency of reagent.
Stochiometric Coefficient
The number in front of a chemical formula in a balanced equation
Atomic Mass
The total mass of protons, neutrons and electrons in a single atom
Molecular Mass
The sum of atomic masses of all atoms in a molecule. Formula mass is used for compounds
Stochiometric Reactant
A reactant consumed in a reaction
Catalytic Reactant
A reactant not consumed in a reaction
