Answer 2

1. Bone charcoal    - c) "decolorization of sugar".

2. Gas carbon        - e) the "deposits formed on the roofs of the retorts"

                                    during the destructive distillation of coal.

3. Diamond             - f) consists of "hexagonal layers of carbon atoms".

4. Fullerene            - b) "yellow spherical ball".

5. Coal                    - d) formed by "slow decomposition of plants".

Explanation:

• Bone charcoal is produced by the heating bone in the "presence of a small amount of the air". It is used for the decolorization and the filtration process. It is also used to remove the colored impurities of the sugar-based solutions
• Gas carbon can be found when petroleum is heated in a closed container under high temperatures.
• Diamond is the solid form of the carbon and it is arranged in the form of a crystalline structure.
• These molecules are formed by the carbon molecules. It is an allotrope which has carbon molecules and consists of single or double bonds.
• Due to pressure and the heat over a "long period of time" on the plants, ferns, and mosses the oxygen left out and remains carbon makes the coal.
