- 2. it is a branch of chemistry that studies and uses instruments and methods used to separate identify and quantify matter.
- 3. it is a branch of chemistry that studies the chemical processes within and relating to living organisms. Biochemical processes give rise to the complexity of life.
- 6. it is a branch of chemistry that studies the structure properties and reactions of organic compounds which contain carbon in covalent bonding. Study of structure determines their chemical composition and formula.
