<p>Ryannayr: created the page and added the equation</p> <hr /> <div>Glycerine, chemically called glycerol, is a sweet tasting, colorless, odorless, and viscous liquid. It is naturally occuring as the backbone of all triglycerides, and is most commonly produced as a biproduct of soap or biofuel in the reaction depicted below. The production of soap is the same process without methanol.<br /> [[File:Glyc.jpg|thumb|The chemical equation for the production of biodeisel. The catalyst is lye (NaOH)]]</div>

<p>Ryannayr: added the information about the hardness of coal and sandstone for comparison</p> <hr /> <div>{{distinguish|Charcoal}}<br /> [[File:Coal Transported to the nearby Meremere Power Station, 1966.jpg|thumb|250px|Maramarua Open Cast Coal Mine in New Zealand, 1966]]<br /> <br /> '''Coal''' is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly [[carbon]] with variable amounts of other elements, chiefly [[hydrogen]], [[sulfur]], [[oxygen]], and [[nitrogen]]. Coal is formed when dead plant matter decays into [[peat]] and is converted into coal by the heat and pressure of deep burial over millions of years. Coal is primarily used as a [[fuel]]. Coal is very soft ranking from 2 to 4 on the mohs hardness scale, while sandstone ranks from 5 to 7.<br /> <br /> == Dependencies ==<br /> <br /> * [[Carbon]]<br /> * [[Peat]]<br /> ** '''Coal'''<br /> ** [[Fuel]]<br /> <br /> == See also ==<br /> * [[Raw material]]<br /> * [[Activated charcoal]]<br /> * [[Carbon dioxide]]<br /> *[[Charcoal]]<br /> *[[Fire]]<br /> <br /> == References ==<br /> {{wa|Coal}}<br /> <br /> [[Category:Fuel]]<br /> [[Category:Hydrocarbons]]<br /> [[Category:Stubs]]</div>
