Question

Coke is almost a pure form of carbon. (T / F)
A. True
B. False

Answer 1

Hint: Carbon forms a huge number of compounds with a large number of elements. It is the only atom that has a high com binning capacity to form compounds and molecules with other atoms and elements.

Complete step by step solution:
Coke is a fuel utilized principally in shoot heaters to diminish iron oxide to deliver iron. It contains carbon and is like coal. It is produced using coal by cooking out things that are not carbon. Coke is a result of damaging refining of coal. This is done in an airless heater or broiler (oven) at temperatures as high as yet for the most part around. This heating drives off unstable pieces of coal, like water, gas, and tar. Coke is a practically unadulterated type of carbon.
The calorific worth (heat energy delivered when fuel is singed) of coke is around 56,000 kilojoules/kilogram. Coke stove at smokeless fuel plant, Abercwmboi, South Wales, and 1976 Coke is utilized as a fuel and as a decreasing specialist in purifying iron metal in an impact heater. The carbon monoxide delivered by its burning decreases iron oxide (hematite) to the iron item. In spite of the fact that coke is more costly than coal, it very well may be utilized in family units as a perfect fuel, generally liberated from smoke and contaminations. At the current day, its utilization in homegrown warming has been not as much as oil or gas, however, in the twentieth century, it was regularly utilized in kitchen ovens.
Hence, option (A) is correct.

Note:
Actually the purest form of carbon is diamond because the composition of the diamond is homogeneous and is consistent throughout but among the given options coke is purest.
