WHAT IS CHEMISTRY? J

>> A study of MATTER

• Structure
  
• Properties (Chemical and Physical)
  
• Composition (Atoms, molecules)
  
• Changes (Chemical Reactions)
  

Branches of Chemistry

1. Inorganic Chemistry
   
   1. All elements except CARBON
      
2. Organic Chemistry
   
   1. Study of Carbon and its compounds
      

      EXCEPT: Oxides of carbon (CO² and CO)
      

          Bicarbonates (NaHCO₃) and Carbonates (CaCO₃ – solid material in teapot, kanang kung magboil ug water)
      

3. Analytical Chemistry
   
   1. Identification of the components both QUALITATIVE¹ (description) and QUANTITATIVE² (how much) of a substance
      
      1. If you want to know if the chemical is ACID OR BASE (description)
         
      2. If you want to know how ACIDIC it is (how much)
         
4. Physical Chemistry
   
   1. Physical properties that underlie the structure and chemical transformation of matter
      
5. Biochemistry
   
   1. Chemistry of the living systems, both plants and animals.
