A chemical process refers to a series of steps that involve the transformation of substances through chemical reactions. These processes can include changes in the composition, structure, or energy of materials. Common examples include combustion, photosynthesis, and fermentation, where reactants are converted into products with distinct properties. Chemical processes are essential in various industries, such as pharmaceuticals, agriculture, and energy production. They enable the creation of new materials, the synthesis of drugs, and the conversion of raw materials into usable forms. Understanding these processes helps scientists and engineers develop efficient methods for producing and utilizing chemicals.
