Chemistry - Page 3

Chemistry is the branch of science that studies the composition, structure, properties, and changes of matter. It encompasses the investigation of substances, their interactions, and the reactions that occur between them. Chemists analyze how atoms and molecules combine, rearrange, or break apart during chemical reactions to form new substances. The field of chemistry is often divided into several sub-disciplines, including organic chemistry (the study of carbon-containing compounds), inorganic chemistry (the study of inorganic compounds), physical chemistry (the study of the physical principles underlying chemical systems), analytical chemistry (the analysis of substances to determine their composition), and biochemistry (the study of the chemical processes within and related to living organisms). Chemistry plays a critical role in various applications, including medicine, energy, materials science, and environmental science, impacting everyday life and technological advancement.
