Welcome I wish to welcome you all to the chemistry department. Chemistry is the basis for life. Everything we see depends on chemistry.
Chemistry is part of science.
Chemistry is closely related to the other branches of science. Biology, for example, is based on principles of chemistry. We are made of chemical substances. Chemical changes are happening in our eyes, lungs, and blood. Your skin, bones, hair, and everything else that is part of your body consist of combinations of chemical substances.
