A Study of chemistry enables those who study it to acquire certain scientific skills such as handling of laboratory apparatus, performing experiments with ease, and thinking scientifically. The application of knowledge and skills gathered through the study of science is called technology. Scientists in the field of chemistry are called chemists.
