purest form of carbon is -
(a)coal
(b) charcoal
(c)coke
(d)all of these
Answers
Diamond is the purest form of carbon since its composition is homogenous and consistent throughout, but among the alternatives, coke is the purest form
Explanation:
Coke is a grey, hard, and porous fuel with high carbon content and few impurities that are produced by burning coal or oil in the absence of air (a destructive distillation process). It is a vital industrial commodity that is mostly used in the smelting of iron ore, but it is also utilized as a fuel in stoves and forges where air pollution is a concern. Coke, for example, is a coal-based fuel with low impurities and a high carbon concentration. It's a solid carbonaceous material made from low-ash, low-sulfur bituminous coal after destructive distillation.
Coal is a flammable black or brownish-black sedimentary rock with a high carbon and hydrocarbon content. Because coal takes millions of years to create, it is classified as a nonrenewable energy source. As a result of the pressure and heat, the plants were transformed into coal.
Charcoal is a light black carbon residue made by burning wood (or other animal and plant materials) in a low-oxygen environment to remove all water and volatile constituents. The soot and smoke commonly given off by wood fires result from incomplete combustion of that volatiles.
All of these options are ruled out when it comes to the purest form of carbon.
