Closer Look At Carbon, Homogeneous # #, Heterogeneous - Coggle Diagram

- - - - Incomplete combustion
        Incomplete combustion occurs if there is insufficient oxygen, so that less energy is produced. The products of the reaction include carbon monoxide and carbon (soot).
    - - Catalytic cracking
        A refining process in which long chain or more complex hydrocarbons, such as oil, are broken down under pressure, heat and in the presence of a catalyst. This produces more useful compounds with shorter chain length.
  - - - Elements
        A substance made up of only one kind of atom.
        
        Native element
        An element that is so stable that it is found in nature as the pure element, e.g., sulfur, gold.
      - Ion
        A particle that is charged due to addition or removal of electrons from a neutral atom.
    - - Molecule
        Two or more atoms chemically combined together in fixed proportions.
- - - - Living things
      - Photosynthesis
        A series of chemical reactions which occur in the chloroplasts of green plants. Carbon dioxide and water combine in the presence of light and chlorophyll to produce sugars and oxygen.

        Carbohydrate
        A large molecule containing only carbon, hydrogen and oxygen. e.g., glucose, starch.
        
        Cellulose
        A carbohydrate composed of glucose monomers. It is the main constituent of plant cell walls.
    - - Surface and deep ocean
    - - Coal
      - Crude Oil
        
        Hydrocarbon
        An organic compound composed entirely of carbon and hydrogen. Most hydrocarbons we use originate from crude oil.
      - Carbonate
      - Natural Gas
        
        Liquid petroleum gas
        A flammable mixture of hydrocarbon gases containing propane or butane (LPG); used as a fuel in vehicles and heating appliances.
      - Petroleum
        A mixture of gaseous, liquid, and solid hydrocarbons that occurs naturally beneath the earth's surface. It can be separated into fractions including natural gas, gasoline, naphtha, kerosene, paraffin wax, and asphalt and is used as raw material for a wide variety of purposes.
    - - Green house effect
        
        Greenhouse gases
        Greenhouse gases such as methane, nitrous oxide, carbon dioxide, ozone and water vapour are found in the Earth's atmosphere.
