Formation of Coal (Process) Coal is composed of carbon, hydrogen, oxygen, nitrogen, sulphur, moisture, and incombustible mineral matter (, ash). Fluorinated gases are not formed by coal combustion. Coals are formed from the accumulation of vegetable debris in specialized environments. Obtaining coal from the mines is a difficult job.

Discuss Coal is a darkshaded rocklike fuel in which the substance of carbon can fluctuate somewhere in the range of 70 and 90%. It is framed by the deterioration of vegetation under intensity and strain. The course of coal arrangement is called carbonization, and the time span during which this cycle happens is known as the carboniferous age.

Question 2: Is coal a natural resource? Answer: Yes, coal is a natural resource since it is made up of dead and rotting vegetation and plants that have been buried for millions of years at high temperatures and pressures. Question 3: Describe the Process of Petroleum Refinement. Answer: The refining of oil is a highly mechanized process.

Law of Conservation of Mass. The law of conservation of mass was created in 1789 by a French chemist, Antoine Lavoisier. The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted.

In a process called photosynthesis, these organisms convert light energy from the sun into chemical energy stored in sugars. However, the light energy doesn't produce the atoms that make up those sugars—that would break the Law of Conservation of Mass —it simply provides energy for a chemical change to occur.

Mining coal. Coal miners use large machines to remove coal from the earth. Many coal deposits, called coal beds or seams, are near the earth's surface, but others are deep mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.
