Make a mnemonic up, could be something stupid like:
LPG
Petrol
Naphtha
Kerosene
Diesel
Oil
Bitumen

Decontamination is needed in order to what?
Decontamination is a process to remove contaminants from people and equipment. It is necessary to decontaminate in order to keep everyone safe and free of bacteria or other harmful substances.
What are the substances that interact during a chemical reaction?
The substances that are combined in a chemical reaction are called the reactants, and the end substances are called the products.Compounds involved in a process but not found in the end products are called catalysts.
Which is heavier clay or silt?
silt because there is a specific oder these substances go in order by. This goes from greatest mass to least mass: sand, silt , clay
How do you separate ethanol from a mixture of water and ethanol?
Two cases of course depends what you want to keep. Case 1: Just separate them, don't care what remains, as long as they are separated. Well, heat them up, not a lot, a bit. Why? Think. Case 2: Keep the ethanol but not water. This is tricky, I can't help you.
What is the juxtaposition of strongly dissimilar elements?
The juxtaposition of strongly dissimilar elements means two totally different substances or objects that have been placed together in order to someone can see how much different they are.
Can liquids with similar boiling points be separated using fractional distillation?
No, due to the fact that fractional distillation uses the difference in boiling points of liquids to seperate them, therefore in order to perform fractional distillation there should be a difference of at least 1degree centigrade
Why do chemicals separate out in a particular order?
In fractional distillation, the substances in a mixture are heated to their boiling points. Different substances have different boiling points, so will be separated at different times. The answer to your question is simply because they have different boiling points.
What is a distillation disadvantage of fractional distillation?
One of the main sources of all types of energy is from sun.. The sources like fossil fuels, etc r gonna sure disappear some years later.. also its utilisation now also creates serious impact on life of human beings...u can c in many places were its temperature is hike... so installation of other devices for purification s a hard tiring process. so the better option s to use the available source for the purification process will be a good one. so its a advantage...
How are hydrocarbon molecules separated?
using fractional distillation. first crude oil is heated up until it turned to gas and the residue (bitumen) goes through the most bottom pipe to be used for tar macing roads. The fractionating column has different fraction that are at different temperatures (gets colder as you go up). And because hydrocarbons got different boiling point (the longer the hydrocarbon, the higher the boiling point), the gas then travels up and as certain hydrocarbons got to the fraction below their boiling point they turn from gas to liquid and go through the pipe to be used.The fractional distillation goes in this order:-(shortest chain/lowest boiling point)LPGPetrolParaffinLight Gas OilDieselLubricating SubstancesBitumen(longest chain/highest boiling point)Hope this help! (if not don't blame me, I'm only 14!)
How to separate petrolium into fractions?
fractional distillation. you use the boiling point to separate petroleum into its different compounds. the order is asphalt, lubricating oil, jet fuel and diesel fuel, kerosene, and gasoline.
What would be left in the flask when separating alcohol from water using fractional distillation?
In order to separate a mixture of alcohol (ethanol) and water, use a process known as fractional distillation. This technique relies on the principle that the compounds in the mixture have different boiling points. Since ethanol boils at a lower temperature (78.5 degrees C) than water, the alcohol vaporizes while the water remains a liquid. At some point, it will become an azeotropic mixture where the vapor has the same composition as the liquid. A good distillation column will produce an azeotropic mixture of 95 percent alcohol and 5 percent water. This ratio represents the most pure form of ethanol possible with distillation and is widely accepted as an industry standard.
Why kmno4 is added in simple distillation?
you mean water distillation? in order to remove minerals by oxidizing them and contaminants from organic materials including surfactants.
How do you obtain gas?
The company that makes it gets it the same way they get liquid oxygen and liquid nitrogen - fractional distillation of air. A customer who wants some has to special-order it from a welding supply; they can get it for you but unless you live in New York City where there are several neon-sign companies, it's not commonly used.
Why is that slow distillation better than fast distillation?
In order to prevent entrainment or liquid carryover, distillation must be slow. If it is heated vigorously, it will result in loss of products and carry over of other components as liquid.
What is distillation in a unit operation?
distillation is the process of repeated evaporation and condensation of the mixture of two or more miscible solutions in order to separate them by evaluating the boiling point
Why distillation is not used often for cleaning water?
Because when water is distilled it losses all the essentials salts and minerals.
Why is it necessary for us to know the names and functions of laboratory apparatus?
Simply because each piece of apparatus has set functions ! For example - it's no good trying to separate chemicals with different boiling points in an ordinary flask. You need the addition of the fractional distillation tube, so that the one with the lower boiling point will condense back into the flask. You would need to know what a fractional distillation tube was - and what it looked lke in order to select the correct piece of equipment !
