Chemistry is the scientific discipline that deals with the study of matter, its properties, composition, structure, behavior, and the changes it undergoes during chemical reactions. It is often referred to as central science because it connects and overlaps with other branches of science, such as physics, biology, and geology.9th Class Chemistry Notes 2024 All Chapters
