Crude oil
crude oilMixture of hydrocarbons, mainly alkanes, formed over millions of years from the remains of ancient dead marine organisms. is a natural resourcesMinerals that have been made through the formation of the world that can be used for human benefit. that is a complex mixtureTwo or more substances that are not joined together. The substances can be elements, compounds, or both. of hydrocarbons. The carbon atoms in these molecules are joined together in chains and rings. In the ball and stick models of simple hydrocarbons below, carbon atoms are black and hydrogen atoms are white.
Crude oil is a finite resourceA resource that is no longer being made or which is made extremely slowly, such as crude oil and metal ores. because it forms extremely slowly over millions of years and cannot quickly be replaced. However, crude oil is an important source of:
- fuelMaterial that is used to produce heat, like coal, oil or gas.
- feedstockA raw material used to provide reactants for an industrial reaction. for the petrochemicalSubstance made from crude oil using chemical reactions. industry
A feedstock is a raw material used to provide reactants for an industrial reaction. A petrochemical is a substance made from crude oil using chemical reactions. For example, ethene is produced from crude oil. It is used as feedstock to make poly(ethene), a polymerA large molecule formed from many identical smaller molecules known as monomers..
