Theoretical oxygen
WebbStoichiometry ( / ˌstɔɪkiˈɒmɪtri /) is the relationship between the quantities of reactants and products before, during, and following chemical reactions . Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products, leading to the insight that the relations among ...
