What are the reason that in most distillation that the total volume of liquid obtained is not equal to the volume that was introduced into the flask?

Two reasons - the main one is usually loss of vapour from the system, the other is that mixing two liquids will rarely produce a total volume that is the same as before mixing. Differences in intramolecular and intermolecular bonding mean that the molecules arrange themselves differently between pure liquid and mixture. Try mixing a known volume of water with a known volume of alcohol - there will be a big change in the total volume if you do it carefully and accurately.

Explain the differences between fractional and simple distillation which is more efficient how the efficiency could be enhanced What is the purpose of adding boiling stones?
The difference is that simple distillation will be used to separate substances within mixtures that have significantly different boiling points; whereas, with fractional distillation, the boiling points are closer and separation must be cared for differently. This is the reason why you must employ the use of an additional piece of apparatus called the fractionating column when undergoing fractional distillation. Based on what is stated above, the more efficient method would have to be Fractional Distillation because it essentially separates the parts of the mixture much more precisely. You could enhance fractional distillation by using boiling stones. The reason for adding the boiling stones is to calm down the boiling of the liquid mixture. You really do not want the boiling to become too violent as is the case with "bumping" which is when the air pressure inside the liquid increases so rapidly that it will literally BUMP the glass while it is trying to expel the excess air pressure. Normally only th air will be relieced out from the opening of the container such as the top (ie. the surface of the liquid), but too much air and too little surface area at the top will cause air to be reliese radially outward and strike the sides of the container. Just try boiling eggs real fast with the stove on high and never turn it down; you'll see it happen.
What is the reason for the existence of three states of matter?
solid, liquid and gas
When deodorant is inside of its can is it a solid or liquid or gas?
its a liquid because its compressed and the reason that it is cold is because it has to move from liquid to gas, this movement takes energy and this energy comes from itself.
Two reasons why petroleum is not a mineral?
One reason is that it is liquid while minerals are always solid. The another reason is that it came from organic materials.
What is the reason for yellow colour of urine?
The reason for urine having a yellow color is made up of a pigment called urochrome. The color depends on the amount and type of liquid a person consumes.
Would distillation or filtration produce the purest water from river waterGive a reason?
Because distillation produces vapour and impuritites can not leave with the vapour
Liquid be seen running from the bottom of the distillation column back into the distilling?
The reason it happens because the lower boiling point substance vaporizes and crosses over while the other substance is waiting for its boiling point to reach
Can nitrogen and its components be separated by fractional distillation?
There are no components to Nitrogen. For this reason your question makes no sense.
Why is there a Top Gear Top Dog Is she there for a medical reason?
She was introduced for entertainment purposes. No particular reason. WTD, why would there be a medical reason?!?!?!?!

Is water a liquid and a gas?
No, it can only be liquid the reason why is that gas floats around and liquid holds the shape of its container. So water can only possibly be liquid.

Can liquid soap prevent ice?
Yes liquid soap can stop ice. The reason is because of the cleaning OILS in the soap.
