The art or process of calculating the atomic proportions, combining weights, and other numerical relations of chemical elements and their compounds.

The relationship between the weights of the reactants and the products of a chemical reaction.

the process by which the quantities of the substances involved in a chemical reaction are related and calculated

that portion of chemistry dealing with numerical relationships in chemical reactions; the calculation of quantities of substances involved in chemical equations.

proportions in which elements are combined in compounds.

The number of species of each type of element in the formula for a compound or reaction.

The quantitative relationships among the reactants and products in a chemical reaction as expressed by the equation for the reaction

the proportions in which the reagents combine in a chemical reaction. A reaction is termed stoichiometric when the quantities of reagents occur in the same molar proportions as the chemical equation

(chemistry) the relation between the quantities of substances that take part in a reaction or form a compound (typically a ratio of whole integers)

The study of the relationships between amounts of products and reactants.

Study of the mathematics of the material and energy balances (equilibrium) of chemical reactions.

the proportions in which species make up a balanced reaction, the proportions in which atoms occur within a specific chemical species.

The study of the quantitative relationships between reactants and products.

The quantitative relationship of chemical composition in chemical reactions, resulting from the conservation of mass, atoms and electrons.

The numerical coefficients in front of each chemical species in a balanced chemical reaction.

determines the molar ratios of reactants and products in an overall chemical reaction. We express the stoichiometry as a balanced chemical equation. For kinetics it is convient to write this as products minus reactants: npP + nqQ - naA - nbB (instead of the conventional equation naA + nbB --- npP + nqQ). This indicates that na and nb moles of reactants A and B, resp., produce np and nq moles of products P and Q.

The relative proportions in which elements form compounds or in which substances react.

Ratios of atoms in a compound. Ratios of moles of compounds in a reaction. A branch of chemistry that quantitatively relates amounts of elements and compounds involved in chemical reactions, based on the law of conservation of mass and the law of definite proportions.

Description of the quantitative relationships among elements and compounds as they undergo chemical changes.

Chemical reactions, typically associated with combustion processes; the balancing of chemical reactions by providing the exact proportions of reactant compounds to ensure a complete reaction; all the reactants are used up to produce a single set of products.

Stoichiometry (sometimes called reaction stoichiometry to distinguish it from composition stoichiometry) is the calculation of quantitative (measurable) relationships of the reactants and products in chemical reactions (chemical equations).
