space, whose dimensionality equals the number of linearly-independent chemical reactions.This is necessarily less than the number of chemical components, since each reaction manifests a relation between at least two chemicals.For example it can be expressed as molar fraction, volume fraction, mass fraction, molality, molarity or normality.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 quantities of reactants and products typically form a ratio of positive integers.
RU PROVERKA-DOSTOVERNOSTI-SMETNOY-STOIMOSTI-STROITELSTVA. Stoichiometry rests upon the very basic laws that help to understand it better, i.e., law of conservation of mass, the law of definite proportions (i.e., the law of constant composition), the law of multiple proportions and the law of reciprocal proportions.In general, chemical reactions combine in definite ratios of chemicals.Whether a reaction actually will go in the arbitrarily selected forward direction or not depends on the amounts of the substances present at any given time, which determines the kinetics and thermodynamics, i.e., whether equilibrium lies to the right or the left. k occur whenever the first of the reactants is depleted for the forward reaction; or the first of the "products" is depleted if the reaction as viewed as being pushed in the reverse direction.This is a purely kinematic restriction on the reaction simplex, a hyperplane in composition space, or N?
