A STUDY ON USAGE OF SOCIAL NETWORKING SITES FOR ACADEMIC PURPOSE BY SECONDARY LEVEL STUDENTS

Abstract

Chemistry is a branch of science, which concerns itself with the composition, properties, constitution and mutual interaction of different kinds of matter. The three major branches of chemistry are Organic, Inorganic and physical. The other branches of chemistry are Nuclear chemistry which deals with nuclear reactions, artificial transmutation of elements and radioactive isotopes, Biochemistry which describes the reactions of living processes in health and disease. Analytical chemistry deals with methods of analysis applicable to different types of compounds. Industrial or technical chemistry which applies principles of chemistry in the large-scale manufacture of different elements and compounds. Agricultural chemistry is devoted to the study of soil. water, fertilizers and compounds recovered from plants. Some other branches such as polymer chemistry, pharmaceutical chemistry, theoretical chemistry, applied chemistry, forensic chemistry etc. Chemistry plays a very prominent role in our daily life. It is of greater importance in industries. Chemistry is useful in extraction of petrochemical products, and manufacture of a never ending list of products like fertilizers, synthetic fibers, synthetic rubber, new electrical insulators, new metal alloys. New radioactive isotopes used in diagnosis of disease, synthetic vitamins, hormones, sulpha-drugs, antibiotics, steroids, tranquilizers, antimalarials, antiseptic, dyes, insecticides, fungicides, synthetic protein foods. etc. have revolutionized the modern living and hold out hope of a better future.
