Stoichiometry is a branch of chemistry that deals with the quantitative relationship between the reactants and products in a chemical reaction. It involves calculating the amount of reactants required or products produced in a chemical reaction based on the mole ratio of the substances involved.
The conservation of mass is a fundamental law in chemistry which states that the total mass of reactants in a chemical reaction must be equal to the total mass of the products. In other words, mass cannot be created or destroyed during a chemical reaction, it can only be transformed from one form to another.
Stoichiometry is predicted by the conservation of mass because the mass of the reactants in a chemical reaction must equal the mass of the products. This means that the number of atoms of each element in the reactants must be equal to the number of atoms of each element in the products. Therefore, the mole ratios of the reactants and products in a balanced chemical equation must also be equal, since the number of atoms of each element is directly related to the number of moles of the substance.
Using stoichiometry, we can predict the amount of products that will be formed in a chemical reaction based on the amount of reactants present and the mole ratio between them. This allows us to determine the most efficient way to produce a particular product, as well as to calculate the amount of reactants required to produce a certain amount of product. All of these calculations are based on the conservation of mass, which is a fundamental principle in chemistry.
