Chemical sciences encompass the study of matter, its properties, and the changes it undergoes during chemical reactions. This field includes various branches such as organic chemistry, which focuses on carbon-containing compounds, and inorganic chemistry, which deals with minerals and metals. Chemical scientists explore how substances interact, helping to develop new materials and medicines. In addition to organic and inorganic chemistry, chemical sciences also include physical chemistry, which examines the physical properties of molecules, and analytical chemistry, which involves techniques for identifying and quantifying substances. Together, these branches contribute to advancements in industries like pharmaceuticals, agriculture, and environmental science.
