Extreme pressure and geological periods of time are required.
Carbon Dioxide is CO2, or 1 carbon atom for 2 oxygen atoms. To convert carbon to carbon dioxide, simply introduce energy to carbon in the presence of oxygen, i. e. burn coal.
To convert proximate analysis of coal to ultimate analysis, use the Dulong formula as follows: Carbon = 0.75*(fixed carbon + [volatile matter/100]); Hydrogen = 0.06volatile matter; Oxygen = [moisture/100] + 0.3sulfur - carbon - hydrogen; Nitrogen = volatile matter/100 * 0.01. This formula estimates the ultimate analysis (C, H, O, N) from the proximate analysis (moisture, volatile matter, fixed carbon, ash).
coal is made out of carbon because u need carbon to make coal
Carbon in coal is oxidized to form carbon dioxide when coal undergoes combustion.
coal is mainly carbon....
No, coal is not a carbon sink. In fact, burning coal releases carbon dioxide into the atmosphere, contributing to climate change.
When coal is burnt the chemical change combines carbon from the coal with oxygen from the air to produce carbon dioxide.
No. But burning coal will likely produce carbon monoxide.
The main element in coal is carbon.
The main element in coal is carbon.
pure carbon is coal, also diamonds are coal that was under a lot of pressure. so both diamonds and coal are pure carbon.
Coke is a relatively pure form of carbon. Coke is produced in a process designed to remove sulfur and nitrogen compounds from bituminous coal, and to convert tarry materials -- compounds which contain carbon, hydrogen, and possibly a little oxygen -- to carbon. The coking process is not usually designed to get rid of soil nor ash from coal, and it is usually not particularly effective at doing so. There are many different grades of coal, but none of them are particularly pure forms of carbon. Anthracite, the highest grade, is 92-98% carbon, bituminous coal 60-75% carbon, while lignite, "brown coal", is typically only 25-35% carbon.
