Stoichiometric is a term derived from the Greek words stoicheion, meaning element, and metron, meaning measure. In chemistry, it refers to the quantitative relationship between reactants and products in a chemical reaction. This relationship is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.

Stoichiometric calculations are used to determine the exact amounts of reactants needed to react completely with a given amount of another reactant, or to predict the amount of product that can be formed. These calculations are performed using balanced chemical equations. A balanced chemical equation represents the reactants and products of a chemical reaction, with coefficients that indicate the relative number of moles of each substance involved.

For example, in the reaction of hydrogen and oxygen to form water, the balanced equation is 2H₂ + O₂ → 2H₂O. This equation tells us that 2 moles of hydrogen react with 1 mole of oxygen to produce 2 moles of water. Using these mole ratios, chemists can calculate how much of one substance is needed to react with a specific amount of another, or how much product will be formed.

Stoichiometry is a fundamental concept in chemistry and is applied in various fields, including industrial chemical processes, analytical chemistry, and environmental science. It allows for efficient and precise control of chemical reactions, minimizing waste and maximizing product yield. Understanding stoichiometry is essential for anyone working with chemical reactions.
