Aug 01, 2007· The chemical formula of gold is Au. Gold atoms are attracted to each other in a crystalline structure that extends out in 3-D. The mass of gold present will determine the number of atoms present.The smallest discrete unit of gold found in nature is Au (by the way, Au is derived from the latin name for gold, aurum).
Oct 05, 2010· Best Answer: You have an empirical formula, meaning the lowest ratio of elements. Since that formula gives a mass of 52, multiply by three to get C9H6N3, MW around 156.
Feb 02, 2009· For the best answers, search on this site https://shorturl.im/awUfr Chemical symbol for carbon is C It is a group 14, nonmetallic, tetravalent element, that presents several allotropic forms of which the best known ones are graphite (the thermodynamically stable form under normal conditions), diamond, and amorphous carbon.
Nov 30, 2007· Best Answer: Coal is not actually a compound, but rather a mixture of compounds and so it does not have a chemical formula. However depending on the type of coal, it is composed of between 50- carbon, by mass, with the rest being Hydrogen, Nitrogen, Oxygen, and trace amounts of Sulfur.
Oct 08, 2006· In smaller quanitities are the ingredients talc, a mineral which has the formula H2Mg3(SiO3)4 or Mg3Si4O10(OH)2. Also mineral oil, which is made from refining petroleum to obtain alkanes and cyclic paraffins which have a general formula CnH2n+2, where n is greater than 20, meaning they are relatively large molecules.
Oct 30, 2008· Best Answer: well coal can be represented by the letter C for coal but to make sure we don't get confused with coal and carbon we shall use Cx Cx + O2 --> H2O +CO2 or coal + oxygen --> water + carbon dioxide or coal + fire (oxidization) --> water + carbon dioxide
Feb 14, 2007· Best Answer: Chemical. The easiest way to determine this is to try and get the process to reverse. You cannot take CO2 and H2O (the products of burning coal) and make them separate back into coal (C) and oxygen (O2). If you cannot go backwards to get the original material, then it is a chemical change.
Sep 07, 2006· Best Answer: There is no one particular chemical formula for coal. It is mostly carbon, hydrogen - with the degree of saturation being pretty low (i.e. it is mostly carbon). You can view it as CnHm, where n is a high number and m is relatively low. Notable impurities are sulfur and mercury (amongst other ...
Dec 29, 2005· Fly Ash is a very fine ash produced from the combustion of various sources such as coal, and there can be a mixture of components. In short, there is not specific formula definition for fly ash, but it usually contains SiO2 (silicon dioxide) or Fe2O3 (Iron Oxide).
chemical formula of coal? | Yahoo Answers. The chemical equation for the combustion of coal is C + O2 = CO2. In this equation, C represents the carbon in the coal, which reacts with air, represented by O2, to form carbon dioxide, or CO2.
