stoikiometristä

Stoikiometristä is the Finnish word for stoichiometry. 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 allows chemists to predict the amount of product that can be formed from a given amount of reactants, or to determine the amount of reactants needed to produce a desired amount of product.

The fundamental principle of stoichiometry is the mole ratio, which is derived from the balanced chemical equation for a reaction. A balanced chemical equation represents the chemical transformation in terms of the number of moles of each substance involved. For example, in the reaction 2 H2 + O2 → 2 H2O, the mole ratio between hydrogen and water is 2:2 (or 1:1), meaning that for every two moles of hydrogen that react, two moles of water are produced.

Key concepts in stoichiometry include molar mass, which is the mass of one mole of a substance, and limiting reactants, which are the reactants that are completely consumed in a reaction and thus determine the maximum amount of product that can be formed. By applying these principles, chemists can perform calculations to understand and control chemical processes, from laboratory experiments to industrial production.
