What is the eyes main functions?
To see. Vision is the main function.
Why are boiling chips placed in distilling flask during distillation?
They provide a site for nucleation and prevent the liquid from superheating.

Is the distilling of water a chemical change?
Distilling is a physical change.
What size boiling flask would one use to distill 75m of ethanol?
For distilling 75 mL of ethanol, a boiling flask with a capacity of at least 100 mL would be suitable. The flask should have some extra capacity to prevent overflowing and accommodate any necessary headspace during distillation.
What is the function distilling flask?
The distilling flask helps in the separation of two liquids.
What are the uses of distilling flast?
A distilling flask is used for distilling. Surprise, surprise, surprise!
Uses of distilling flask?
used of holding liquid and heat = =
Why should the distilling flask be filled to no less than one thirds of its capacity?
If the neck of your flask is short, you don't want to fill the flask too high (more than about 1/2), or else liquid from the flask will enter your distilling tube and get distilled out when you heat it. Remember the idea of a distillation is to heat up your substance to the vapor phase and let the vapor diffuse toward the distillation tube so that only purified product drips into the collecting flask.
How do you know when to stop distilling?
You stop distilling when the temperature no longer changes and there is a small amount of liquid left in the boiling flask. You should not boil it dry as it will weaken the glass and it may break.
What is a distillation flask?
A distilling flask is a round bottom flask that often has two openings, and some of them have a long neck.it is used for distillation processes. See the Web Links to the left for pictures and more information about how to use a distilling flask.
What is the main cause of heat loss in a normal thermos flask?
The main heat loss in a good thermos flask, is due to heat conducted through the material. (Glass or Stainless Steel). There should be little heat lost through the vacuum of the flask.
To distil sea-water you must first.?
collect sea water in distilling flask. boil water. steam escapes, salt remains behind. use physical means to separate physical mixtures.
What is a lab flask for?
there are many types of flasks present in chemistry lab. some can be accurate for volume measurment others for some different functions as storage for example flasks commonly present is " volumetric flask- erlenmeyer flask - florence flask " the volumetric is accurate method for volume measurement erlenmeyer or conical florence or rounded has the same functions "storage ,, stirring ,,heating ,,mixing " the only difference is the rounded one is less stable as the base is smaller
What is the eyes main functions?
To see. Vision is the main function.
What are the uses of a flask?
The round bottoms on these types of flasks allow more uniform heating and/or boiling of liquid. Thus, round-bottom flasks are used in a variety of applications where the contents are heated or boiled. Round-bottom flasks are usually used in distillation by chemists as distilling flasks and receiving flasks for the distillate One-neck round-bottom flasks are used as the distilling flasks in rotary evaporators.This flask shape is also more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface.
Why are boiling chips placed in distilling flask during distillation?
They provide a site for nucleation and prevent the liquid from superheating.
