Some Basic Concepts of Chemistry Questions and Answers - Description
Dear readers, here we are offering Some Basic Concepts of Chemistry Questions and Answers PDF to all of you. Chemistry or Chemistry is an important branch of science. In this, the composition, structure, properties of substances, and changes during chemical reactions are studied. The dissolution of the word chemistry is – juice + ion. It means; Study of juices (liquids). In chemistry, atoms, molecules, crystals (rays) of substances, and the energy released or used during chemical processes are also studied. Chemistry has an important contribution to every area of life. It is used in the manufacture of fertilizers, pesticides, medicines, soaps and detergents, toothpaste, etc.
For example, cis-platin is an anticancer compound and AZT is used in the treatment of AIDS. It is also helpful in meeting the daily needs of human beings like clothes, food, etc. In chemistry, along with the properties of the composition-structures of elements and compounds, the changes in them are also studied. Also, the energy that is released or absorbed during these changes is also studied in chemistry.
