What is the quantitative relationship between reactants and products in a chemical reaction known as?

The quantitative relationship between reactants and products in a chemical reaction is known as stoichiometry. This concept is fundamental to chemistry, as it provides a framework for understanding how substances interact in a chemical reaction. Stoichiometry is based on the balanced chemical equation, which details the number of moles of each reactant and product involved in the reaction. By using stoichiometric coefficients from the balanced equation, one can calculate how much of each reactant is necessary to produce a certain amount of product or how much product can be formed from given amounts of reactants.

Understanding stoichiometry is crucial for predicting the outcomes of reactions, performing calculations related to yield, and scaling reactions for practical applications in laboratory or industrial settings. It allows chemists to quantitatively analyze the efficiency of reactions and make informed decisions about reactant quantities when planning experiments or manufacturing processes.
