Chemistry IX

Class - 9th

Chemistry 

Chemistry is the study of matter, its properties, how and why substances combine or separate to form other substances, and how substances interact with energy. Many people think of chemists as being white-coated scientists mixing strange liquids in a laboratory, but the truth is we are all chemists. Understanding the basic chemistry concept is important for almost everything in our lives.
