Compounds are chemical substances formed by chemical bonds between two or more identical molecules. It also studies the bonding responsible for the formation of these compounds. The factors of energy and entropy are important in the study of chemical processes. Chemical substances are classified on the basis of their structure, phase and composition. They can be analyzed using the tools of spectroscopy and chromatography. Chemistry is divided into a number of significant sub-disciplines such as analytical chemistry, biochemistry, inorganic chemistry, organic ch
