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.
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.
What are the two steps involved in process of in distillation.?
Step 1: heat the solution to the boiling point of the product you're trying to remove by distillation--if you're making fine liquor, you raise the temperature to 173 degrees, the boiling point of ethanol. Maybe a bit higher, but not much. Care is called for. (Many guys who make moonshine raise the temperature until the still starts thumping, causing more than just ethanol to boil off--these extra alcohols are one reason moonshine can kill you. Well, that and some moonshiners like to use car radiators as condensers, causing the shine to contain both lead and antifreeze--NOT good! Stay away from moonshine!) Step 2: capture the steam and recondense it into a liquid.
Why is liquid nitrogen used in beer cans over liquid oxygen?
The answer is, liquid nitrogen ISN'T used in beer cans. Nitrogen GAS is. And the reason nitrogen gas is used in beer cans is to emulate draft beer such as one would get out of a keg(as opposed to cask) beer.
Is honey a solid or a liquid?
Honey in not a solid; in fact, it is a very thick liquid. When you try to pour honey out of a jar, as it is very viscous (thick, not easy to pour), it takes a while to come out. It is also very sticky.
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
What is the reason of using beads in the distillation flask when distilling water?
If you put boiling beads in a solution, then it is easier to observe whether the solution begins to boil because the beads will vibrate. During the distillation process it is difficult to distinguish which solution is boiling so that's why they use boiling beads (quite honestly, it doesn't matter to me because I still don't see the difference!)
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?!?!?!?!
Liquid be seen running from the bottom of the distillation column back into the distilling?
This situation could be caused by poor separation in the distillation column, leading to liquid carryover. To address this issue, check the trays or packing in the column for damage or blockages that may disrupt the separation process. Adjusting operating conditions like temperature, reflux ratio, or feed rate might also help improve separation efficiency and prevent liquid from flowing back into the distilling flask.

Is Luke Skywalker going to have a son?
In the books he did have a son. There is no reason to believe a son will be introduced in the films.
Can liquid soap prevent ice?
Yes liquid soap can stop ice. The reason is because of the cleaning OILS in the soap.
Why do cats pee?
The same reason as humans do. They have to get rid of their liquid waste.
