2. Element Elements and Compounds Extraction of Sulphur Non-metals Compounds A compound is a substance composed of two or more elements, chemically combined with one another in a fixed proportion. Water, sugar, salt, carbon dioxide, methane etc are the examples of compounds. Mineral Coal and Mineral Oil Coal COAL Coal is an organic sedimentary rock that forms from the accumulation and preservation of plant materials, usually in a swamp environment. Coal is a combustible rock and along with oil & natural gas it is one of the three most important fossil fuels. Coal has a wide range of uses; the most important use is for the generation of electricity.

Water, sugar, salt, carbon dioxide, methane etc are the examples of compounds. Mineral Coal and Mineral Oil Coal COAL through a microscope Coal forms from the accumulation of plant debris, usually in a swamp environment. When plant debris dies and falls into the swamp the standing water of the swamp protects it from decay. About ten feet of plant debris will compact into just one foot of coal.

Mineral Coal and Mineral Oil Coal Coal is of Four Main Types:- 1.Peat 2.Lignite 3.Bituminous 4.Anthracite Coal is of Four Main Types:- 1.Peat 2.Lignite 3.Bituminous 4.Anthracite Lignite Anthracite Bituminous Peat

5. Element Elements and Compounds Extraction of Sulphur Non-metals Compounds A compound is a substance composed of two or more elements, chemically combined with one another in a fixed proportion. Water, sugar, salt, carbon dioxide, methane etc are the examples of compounds. Mineral Coal and Mineral Oil Coal Peat contains about 28% carbon. It is called rough coal. Wax, acetone, acetic acid, methanol as well as cyclic organic compounds are available from destructive distillation of peat. Peat contains about 28% carbon. It is called rough coal.

6. Element Elements and Compounds Extraction of Sulphur Non-metals Compounds A compound is a substance composed of two or more elements, chemically combined with one another in a fixed proportion. Water, sugar, salt, carbon dioxide, methane etc are the examples of compounds. Mineral Coal and Mineral Oil Coal Lignite contains about 28 to 30% carbon. It contains volatile matter and moisture also. It is used as fuel in railway engines, thermal power stations and small and big industries. Lignite is used to obtain coal gas and coal tar is obtained as residue, in which cyclic hydrocarbons, phenol, cresol and other compounds are present. Lignite contains about 28 to 30% carbon.

Water, sugar, salt, carbon dioxide, methane etc are the examples of compounds. Mineral Coal and Mineral Oil Coal Bituminous coal contains about 78 to 86% carbon. It also contains volatile matters and moisture in some proportion. It is used as fuel in the production of steel and in production of electricity. Bituminous coal contains about 78 to 86% carbon. It also contains volatile matters and moisture in some proportion. It is used as fuel in the production of steel and in production of electricity.

Water, sugar, salt, carbon dioxide, methane etc are the examples of compounds. Mineral Coal and Mineral Oil Coal Anthracite is a matured form of mineral coal. It contains about 94 to 98% carbon. When pure anthracite burns, smoke or smell is not produced and the amount of residue is very less. Hence, anthracite is considered as the best type of coal.

Water, sugar, salt, carbon dioxide, methane etc are the examples of compounds. Mineral Coal and Mineral Oil Coal When coal is heated without air, it does not burn but produces many by-products. This process of heating coal in the absence of air is called destructive distillation of coal.

10. Element Elements and Compounds Extraction of Sulphur Non-metals Compounds A compound is a substance composed of two or more elements, chemically combined with one another in a fixed proportion. Water, sugar, salt, carbon dioxide, methane etc are the examples of compounds. Mineral Coal and Mineral Oil Coal The hot gases produced during destructive distillation of coal are known as coal gas. The coal remained in the retort is known as coke. It is used for burning and in preparing steel from iron. The black sticky liquid substance which is insoluble in water and settles down is called tar. One 1000 kg of coal produces,700 kg of Coke, 100 liters of Liquor Ammonia, 50 liters of Coal Tar and 400 m 3 of Coal gas.

11. Element Elements and Compounds Extraction of Sulphur Non-metals Compounds A compound is a substance composed of two or more elements, chemically combined with one another in a fixed proportion. Water, sugar, salt, carbon dioxide, methane etc are the examples of compounds. Mineral Coal and Mineral Oil Coal Coke is black-brown coloured hard and porous substance. It contains about 80% carbon. It is used as smokeless fuel in the production of water gas. Coke is a fuel which can be used in homes and factories. But it is largely used as a reducing agent in the extraction of metals from their ores. It is also used in making fuel gases like water gas which is a mixture of carbon monoxide and hydrogen.

Water, sugar, salt, carbon dioxide, methane etc are the examples of compounds. Mineral Coal and Mineral Oil Coal Coal tar is dark black coloured liquid. Coal tar which is a mixture of different carbon compounds can be used to make soap, fats, dyes plastics perfumes, drugs, pesticides, explosives etc. The coal gas, also called as a town gas is a mixture of hydrogen, methane and carbon monoxide which are combustible making the coal gas an excellent fuel having high calorific values.
