Theater Ballistic Missiles (TBM)
Coal is extracted from the earth through a process called mining. This involves digging deep underground or using surface mining methods to access coal deposits. Machinery and tools are used to extract the coal, which is then transported to processing plants for further refinement.

i think it can be used for thermoset moulding and electro-chemical ethching. by okiemute ohwahwa from nigeria.
The chemical commonly used for testing chlorine in water is sodium thiosulfate. This chemical is added to water samples that are being tested for chlorine content to neutralize the chlorine and allow for accurate measurement using colorimetric methods.
Coal does not get refined. Oil gets refined, but coal gets used as it is when it comes out of the coal mine. There is a process called coal gassification by which natural gas can be made from coal, but that is not really a form of refining, and in any event, most coal is simply burned, it is not gassified.
You need big buff legs to mine coal
it comes from lava
Petroleum and coal are largely used in chemical industry or as fuels.
Coal has potential chemical energy which is released as heat when it is burned.
The methods used to predict products of chemical reactions include understanding reaction types, balancing chemical equations, and applying knowledge of chemical properties and reactivity.
The main types of energy in coal are chemical energy, which is released when coal is burned, and potential energy stored within the coal itself. When coal is burned, the chemical energy is converted into thermal energy, which can be used for generating electricity or heating.
The two methods used for mining coal are surface mining and underground mining. Surface mining involves removing layers of soil and rock to access coal deposits near the surface, while underground mining involves tunneling underground to extract coal from deeper deposits.
Coal stores energy in the form of chemical energy that was originally produced by ancient plants through photosynthesis and then stored in the coal over millions of years. When coal is burned, the chemical energy is released as heat energy, which is then transformed into electricity or used for other purposes.
Open cast and mining are the 2 used
Yes, when it is burned (oxidized in air), it releases the chemical energy stored within its chemical bonds.
"Clean coal" primarily from the Powder River Basin, is low in sulfur content compared to other coal sources, and therefor produces less SO2 when combusted. " Clean Coal Technologies" use chemical methods of "scrubbing" SO2 from exiting flue gasses before they can be released to the environment. One byproduct of this technology is gypsum which can be used in wall board for construction.
