Is it how fossil fuels combust and release carbon into the air, which is filled with oxygen, therefore C + O2 ---gt; CO2 ? Or is that completely wrong?
When you burn organic matter you combine that matter with oxygen using heat. Organic matter is carbon based. It can be fossil fuels, but also wood, trash, plastic, paper, food, etc. The carbon and oxygen bond, creating CO2, CO, and other organic compounds. The two elements are bound by the combustion (heat), not because it is released into the air.
divide 2,000 kPa, by g(the acceleration due to gravity); then multiply by π r? (where r 0.15 m, the radius of the piston) Good luck, Donkey Hotei P.s: please select a best answer. Thanks.
Hello Robin. I'm a chemical engineer. hope this answers your question. Carbon dioxide is formed by combustion and by biological processes. These include decomposition of organic material, fermentation and digestion. As an example, exhaled air contains as much as 4% carbon dioxide, or about 100 times the amount of carbon dioxide which was breathed in. Large quantities of CO2 are produced by lime kilns, which burn limestone (primarily calcium carbonate) to produce calcium oxide ( lime, used to make cement); and in the production of magnesium from dolomite (calcium magnesium carbonate). Other industrial activities which produce large amounts of carbon dioxide are ammonia production and hydrogen production from natural gas or other hydrocarbon raw materials. The concentration of CO2 in air and in stack gases from simple combustion sources (heaters, boilers, furnaces) is not high enough to make carbon dioxide recovery commercially feasible. Producing carbon dioxide as a commercial product requires that it be recovered and purified from a relatively high-volume, CO2-rich gas stream, generally a stream which is created as an unavoidable byproduct of a large-scale chemical production process or some form of biological process. In almost all cases, carbon dioxide which is captured and purified for commercial applications would be vented to the atmosphere at the production point if it was not captucaptured transport and beneficial use at other locations. The most common operations from which commercially-produced carbon dioxide is recovered are industrial plants which produce hydrogen or ammonia from natural gas, coal, or other hydrocarbon feedstock, and large-volume fermentation operations in which plant products are made into ethanol for human consumption, automotive fuel or industrial use. Breweries producing beer from various grain products are a traditional source. Corn-to-ethanol plants have been the most rapidly growing source of feed gas for CO2 recovery.
