Key Concepts

Chemical Reaction

A chemical reaction is a process where substances, called reactants, undergo a transformation to form new substances, known as products. This transformation involves the breaking and formation of chemical bonds, and the overall reaction must obey the conservation of mass by having the same number of atoms for every element on both sides of the equation.

Unbalanced Chemical Equation

An unbalanced chemical equation lists the reactants and products of a chemical reaction without ensuring that the number of atoms for each element is equal on both sides. It serves as an initial representation of the reaction and is later adjusted by balancing coefficients to adhere to the law of conservation of mass.

Stoichiometry

Stoichiometry is the quantitative relationship between the amounts of reactants and products in a chemical reaction. It allows for the calculation of reactant consumption and product formation, ensuring that the reaction complies with the conservation laws and practical yield considerations.

Catalysts

Catalysts are substances that accelerate the rate of a chemical reaction by lowering the activation energy required, without undergoing permanent changes themselves. They are especially important in industrial processes, where they enable reactions to occur more efficiently and under milder conditions.
