Petroleum
It is the most important of the fossil fuels. Petroleum occurs under the Earth's crust. It is believed to have formed due to the bacterial action of decomposition on marine animals and prehistoric forests inside the Earth, under conditions of high temperature and pressure. Petroleu..
Fractional Distillation
Separation of petroleum into simpler fractions after the removal of unwanted material..
Distillation
The fermented liquor contains 9-10% of ethanol and is called wash or wort. It is distilled in a Coffey still (Distillation of wash in a Coffey still) to remove water and other impurities present in wash . The Coffey still consists of two tall fractionating column..
Synthetic petroleum
Preparation can be represented as follows: Synthetic petroleum is also a mixture of several alkanes. It is fractionally distilled to obtain petrol, diesel etc. Heavy oil, a fraction of petroleum that is inexpensive is the solvent us..

It is used for separating two liquids in any mixture, which have boiling points within a narrow range of temperatures. In such cases, simple distillation does not give complete separation and a modified version called fractional distillation is employe..
Fractional crystallization or fractional distillation
Fractional crystallization or fractional distillation cannot bring about resolution. This is because the enantiomorphs have identical physical properties. Some of the methods used for resolution are a) Mechanical separation b) Biochemical separation c) Salt formation ..
Fractional distillation of ordinary water
In the partial separation of heavy water from ordinary water, advantage is taken of the small difference in the boiling points of protium oxide (373.2 K) and deuterium oxide (374.3 K). Since the difference in boiling points is very small, a long fractionating column (about 13m) is used f..
Air is a Mixture of Different Gases
. When air is chilled below 0 o C, water vapour gets separated in the form of tiny ice cubes. From liquid air, oxygen and nitrogen get separated by fractional distillation at different temperature..
Mining of petroleum
Petroleum is brought to the surface by drilling a hole in the Earth's crust and sinking pipes deep down through the impervious cap rock. Natural gas first comes out under high pressure. Then, petroleum is pumped out, collected in tanks and transported, for further processing. ..

Even though I don't feel good, the tutor helped me by totally helping me understand!
Very good, Tutor was clear and guided me through the whole algebra problems
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
