Charcoal is an impure form of carbon, created from a variety of things, there is no definite formula for charcoal
EDIT:(acslayder15)
actually charcoal is a compound, it is made up of different types of elements
anyway the chemical formula is C7H4O
(mostly carbon, with some hydrogen and oxygen)
Charcoal is carbon (C) containing many impurities (as ash).
There is no chemical formula!
The chemical formula for disodium guanylate is C10H12N5Na2O8P
A chemical formula is just one molecule. For example, the chemical formula for water is H2O. The chemical formula for ammonia is NH3 A chemical equation contains reactants and products, which are molecules or groups of molecules. For example, what is the chemical equation for the formation of water. 2H2 + O2 ---> 2H2O
o3
When anything is burned a chemical change occurs. The chemical composition of charcoal changes.
Gunpowder is a finely ground mixture of Potassium Nitrate (75%), Sulphur (10%) and Charcoal (15% w/w). The mixture burns extremely quickly, evolving gases which increase the reaction volume and thus make it a powerful propellant.
Charcoal is carbon (C) containing many impurities (as ash).

Chemical Engery
Yes it is, in the sense that virtually anything can be classed as a chemical substance if regarded that way. Coconut charcoal is very porous indeed - more so than charcoal obtained from other sources.
yes charcoal is simply carbon. Though other impurities may be present.
Its a chemical change because the properties of charcoal are changing when fire makes contact with it. It is realising energy and that is one of the most important signs to know if it is a chemical reaction.
