| RENDERING AND ANNOTATION
A. Analytical chemistry deals with the methods of separation. Synthetic chemistry deals with the methods by which complex bodies can be built from simplier substances. Physical chemiststry deals with changes in state and with the motions of molecule. But at the present time the scientists don't maintain this definition. The discovery of X-rays, an electron, and radioactivity marked a new era in all sciences in and in chemistry. It was a very important discovery in science. It plays an important part in the development of geology and physiology, in technology and in chemical engineering. Chemistry deals with medicine and agriculture as they are all concerned with the properties and change of chemical substances. B. The science of chemistry deals with substances. Chemistry is the investigation and discussion of the properties of substances. Common examples of substances are: water, sugar, salt, copper, iron and many others. Chemists study substances in order to learn as much as they can about their properties and about the reactions that change them into other substances. This knowledge is very important as it can make the world a better place to live in, it can make people happier, it can raise their standard of living. Chemists discovered many laws, investigated many important phenomena in life. They produced many artificial substances which have valuable properties. Chemistry has two main aspects: descriptive chemistry, the discovery of chemical facts, and theoretical chemistry, the formulation of theories. The broad field of chemistry may also be divided in other ways. An important division of chemistry is that into the branches of organic chemistry and inorganic chemistry. CHECKLIST Assess your progress in this unit. Tick () the statements which are true. I can give a definition for chemical engineering. I can talk about the most important engineering activities.
