Key Concepts

Conservation of Mass

The conservation of mass is a core principle in chemistry stating that mass is neither created nor destroyed during a chemical reaction. This means that the total mass of the reactants must equal the total mass of the products. This principle underpins the necessity of balancing chemical equations, ensuring that each element's atom count remains constant throughout the reaction.

Stoichiometry

Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in a chemical reaction. It involves using the balanced chemical equation to determine the proportions and amounts of substances needed or produced, which is essential for both laboratory preparations and industrial chemical processes.

Chemical Equation Balancing

Balancing chemical equations is the process of ensuring that the same number of atoms of each element are present on both sides of a chemical reaction. This is achieved by adjusting the coefficients in front of the chemical formulas, which represent the relative amounts of the substances involved. This concept is fundamental in chemical reactions to honor the law of conservation and to express reactions quantitatively.
