Some coal is high in sulfur (S) content, and when it burns, it forms sulfuric acid (H2SO4), a major component of acid rain, by a series of reactions. Balance the equation for the overall conversion drawn below. S(s) + O2(g) + H2O(l) right arrow H2SO4(l).

Qualitative and semiquantitative tests demonstrating the evolution of chlorine have been made by heating chlorides at low temperatures in the presence of sulfur. Quantitative tests on to-. Low-rank coal is defined as consisting of a gross caloric value (e.g. heating value) of less than 24 MJ/kg (moist, ash-free basis) and mean vitrinite reflectance as less than %. Higher rank coals (medium and high rank) are defined as consisting of gross calorific value equal to or more than 24 MJ/kg (moist, ash-free basis) and vitrinite.

Total sulfur content of Illinois coals has been reported from as low as % to more than 7%.
The sulfur content is less than % in a few significant areas; the resources in these areas are estimated to constitute about 8% of the remaining resources.

proportions. For example, the sulfur content of coal may range from low (less than 1 weight percent), through medium (1 to 3 weight percent), to high (greater than 3 weight percent); ash yields may range from a low of about 3 percent to a high of 49 percent (if ash yields are 50 percent, or greater, the sub-stance is no longer called coal).
The United States Environmental Protection Agency regulates the coal ash ponds under the Resource Conservation and Recovery Act (RCRA) and regulations found in 40 CFR PartSubpart D. Illinois EPA's proposed rule includes a permitting program as well as all federal standards for CCR surface impoundments promulgated by the United States.

Your question sounds as if you believe we add sulfur to the coal, which is wrong. Sulfur, to some degree, is present in coal naturally. Just as coal is the natural product of organic material stored for long periods of time below ground under heat.Proceedings of the International Conference on Coal Science, 16–20 SeptemberUniversity of Newcastle-Upon-Tyne, United KingdomPages COAL WETTABILITY FROM SURFACE SITES CHARACTERIZATION: A MICROCALORIMETRIC STUDYAuthor: G.
