Which substance is an almost pure form of carbon obtained from coal?a)...
Explanation:
Coke:
- Coke is an almost pure form of carbon obtained from coal through the process of destructive distillation.
- During destructive distillation, coal is heated in the absence of air to produce coke, coal gas, and coal tar.
- Coke is a porous, hard, and grey substance that is used in the production of steel and other metals.
- It has a high carbon content, making it a valuable material in various industrial processes.
Coal gas, Coal tar, and Bitumen:
- Coal gas is a flammable gas produced during the destructive distillation of coal. It is used as a fuel for heating and lighting.
- Coal tar is a thick, black liquid obtained during the destructive distillation of coal. It is used in road construction and as a base for the manufacturing of chemicals.
- Bitumen is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. It is used in road construction and waterproofing applications.
Therefore, among the given options, coke is the substance that is an almost pure form of carbon obtained from coal.
