Stöhhiomeetrilised

Stöhhiomeetrilised, often referred to as stoichiometric, describes the quantitative relationships between reactants and products in a chemical reaction. It is derived from the Greek words "stoicheion" meaning element and "metron" meaning measure. In essence, stöhhiomeetrilised calculations allow chemists to determine the exact amounts of substances involved in a reaction, based on the balanced chemical equation.

A balanced chemical equation represents the law of conservation of mass, stating that matter cannot be created or destroyed in a chemical reaction. The coefficients in front of each chemical formula in a balanced equation represent the molar ratios of the substances. For instance, in the reaction 2H₂ + O₂ → 2H₂O, the coefficients indicate that two moles of hydrogen gas react with one mole of oxygen gas to produce two moles of water.

Using these molar ratios, one can predict the amount of product formed from a given amount of reactant, or conversely, determine the amount of reactant needed to produce a specific amount of product. This is crucial in various fields, including industrial chemical synthesis, where precise control of reactant quantities is necessary for efficiency and to minimize waste. Stöhhiomeetrilised calculations are fundamental to understanding and manipulating chemical processes.
