Petroleum - Its Uses And Benefits By Sheryl Joaquin | Submitted On October 10, 2007. 33 9 3 4 7 8 9 3 3. Petroleum or crude oil is a naturally occurring liquid found in formations in the Earth consisting of a complex mixture of hydrocarbons (mostly alkanes) of various lengths. Petroleum literally means rock oil; oil that comes from rock.

How Gasoline Works ­ ­Gasoline is made from crude oil. The crude oil pumped out of the ground is a black liquid called petroleum. This liquid contains hydrocarbons, and the carbon atoms in crude oil link together in chains of different lengths. It turns out that hydrocarbon molecules of different lengths have different properties and behaviors. For example, a chain with just one carbon atom in it (CH4) is the lightest chain, known as methane.

- Petroleum or crude oil is a mixture of hydrocarbons, mainly alkanes, formed by the decay of the remains of sea creatures and plants over millions of years. Fractional distillation. The complex mixture of hydrocarbons is separated into smaller mixtures or fractions by fractional distillation (primary distillation).The crude oil is heated and the vapour/ liquid mixture passed into a tower.ombustion of alkanes. In common with all hydrocarbons, alkanes bum in air or oxygen in very exothermic reactions. In the presence of a plentiful supply of oxygen, complete combustion of alkanes occurs to form carbon dioxide and water.

(Citta Vittoriosa) It was renamed Citta ( Civitas ) Vittoriosa after withstanding the Great Siege of 1565 (also known as the first Siege), during which Birgu was the seat of government in Malta. Despite this name change to 'Vittoriosa' well over four centuries ago, most Maltese people still refer to it as ' il-Birgu '.

Petroleum petroleum, rock oil (mid-14c. in Anglo-French), from Medieval Latin petroleum, from Latin: petra : rock + oleum : oil. ) is a naturally occurring, yellow-to-black liquid found in geological formations beneath the Earth 's surface, which is commonly refined into various types of fuels.

Oil (Pure Substance and Mixture) Petroleum is highly flammable and it's formed by hydrocarbons (a compound made of carbon and hydrogen) with the addition of certain other substances, more specifically, sulphur. Also, you can crush zooplankton and algae to make petroleum/gasoline.

Alkanes Methane, ethane, propane and butane are gases and used directly as fuels. Alkanes from pentane up to around C 17 H 36 are liquids. Gasoline is a mixture of alkanes from pentane up to about decane.Kerosene contains alkanes from about n=10 to n=16.Above n=17 they are solids at room temperature.Alkanes with higher values of n are found in diesel fuel, fuel oil, petroleum jelly, paraffin wax, motor oils, and for the highest values of n, asphalt.erosene contains alkanes from about n=10 to n=16.

- Crude oil is a mixture of substances which are mostly hydrocarbons. A hydrocarbon is a compound containing hydrogen and carbon only. Remember the above sentence, you will probably need it in the exam.Do not forget the word only at the end! Since crude oil is a mixture of different hydrocarbon compounds, the different hydrocarbons will have different boiling points. hydrocarbon is a compound containing hydrogen and carbon only.

Chapter 2 Molecules, Ions, and Chemical Formulas However, Petroleum is not an atomic element either. Petroleum is a crude, complex mixture of naturally occurring hydro-carbons and other organic molecular compounds. Therefore, it cannot be represented with one symbol on the periodic table, as it is not a single atom but many atoms, mostly that of hydrogen and carbon.

- Gasoline is a mixture of hydrocarbons, including hexane. Gasoline and water do not mix because the nonpolar hydrocarbon molecules would disrupt the water in such a way as to produce a structure that was actually lower entropy; therefore, the mixture is less likely to exist than the separate liquids.n crudest terms it is the molecule in the mixture with the highest concentration. That is to say if you had a liter of salt and 2 grams of water. In that case, the salt would be the solvent and the water the solute.

What Are Tar Sands? Photo: Pembina Institute. Tar sands (also known as oil sands) are a mixture of mostly sand, clay, water, and a thick, molasses-like substance called bitumen. Bitumen is made of hydrocarbons—the same molecules in liquid oil—and is used to produce gasoline and other petroleum products.

Petroleum Petroleum, complex mixture of hydrocarbons that occur in the Earth in liquid, gaseous, or solid forms. The term is often restricted to the liquid form, commonly called crude oil, but as a technical term it also includes natural gas and the viscous or solid form known as bitumen, which is found in tar sands.
