These are chemicals that contain hydrogen and carbon only. It made from ancient biomass, mainly plankton. Crude oil straight out of the ground is not much use, as there are too many substances in it, all with different boiling points. A combustion reaction is an exothermic chemical reaction between substances, usually including oxygen gas and accompanied by the generation of heat, energy, and light (flame). The products of a combustion reaction depend on the combusted substance. When metals and nonmetals burn in the presence of oxygen, they will give off their corresponding oxides. On the other hand, hydrocarbons give off carbon dioxide and water upon combustion. A hydrocarbon is a compound made up solely of carbon and hydrogen. Hydrocarbons are the primary constituent of fossil fuels, namely natural gas, petroleum, and coal. They are used as fuel because their combustion releases enormous amounts of energy. Since different hydrocarbons have different ratios of hydrogen to carbon, they produce different ratios of water to carbon dioxide [1
