stökiometristen

The term "stökiometristen" is the Finnish word for stoichiometric. Stoichiometry is a branch of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions. It is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.

Stoichiometry involves using balanced chemical equations to determine the relative amounts of substances involved in a reaction. A balanced chemical equation shows the number of atoms of each element on both the reactant side and the product side of the equation, ensuring that the number of atoms of each element is the same before and after the reaction. These numerical coefficients in the balanced equation are known as stoichiometric coefficients.

Key concepts in stoichiometry include mole ratios, limiting reactants, and theoretical yield. Mole ratios are derived from the stoichiometric coefficients and allow chemists to convert between the amounts of different substances in a reaction. The limiting reactant is the substance that is completely consumed first in a reaction and thus determines the maximum amount of product that can be formed. The theoretical yield is the maximum amount of product that can be produced from a given amount of reactants, assuming the reaction goes to completion. Experimental yield, the actual amount of product obtained, is often compared to the theoretical yield to calculate the percent yield of a reaction. Stoichiometry is a fundamental tool for understanding and predicting the outcomes of chemical reactions in both laboratory and industrial settings.
