Stoichiometry involves quantitative relationships between reactants and products in chemical reactions. By interpreting balanced equations, one can determine how much of each reactant is needed or how much product is formed. For instance, from the reaction 2H2 + O2 → 2H2O, two moles of hydrogen react with one mole of oxygen to produce two moles of water. Stoichiometric calculations are crucial for laboratory preparations, industrial processes, and environmental analysis.
