> **A chemical reaction** is a process in which one or more substances, known as reactants, are transformed into new substances called products through the breaking and formation of chemical bonds. During a chemical reaction, atoms are rearranged while the total number of atoms and the overall mass remain conserved according to the law of conservation of mass. Chemical reactions can occur naturally or be induced under specific conditions such as changes in temperature, pressure, light, or the presence of catalysts. They are fundamental to numerous biological, industrial, and environmental processes, including metabolism, drug synthesis, energy production, and material manufacturing. Chemical reactions are commonly classified into several types, including synthesis, decomposition, single-displacement, double-displacement, combustion, and oxidation–reduction reactions, each characterized by distinct reaction mechanisms and products.
