Karen's teacher asked her to get the flask of nickel (II) oxide from the other side of the room. When she got there all the flasks were labeled with formulas only. She should get the flask labeled?
Nickel(II) oxide has the formula NiO.
Where can one purchase a liquor flask?
Liquor flasks are available at many liquor stores as well as major retailers and some clothing stores. In addition, liquor flasks can often be purchased from liquor manufacturers/distillers.
Why is a round bottomed flask used in fractional distillation rather than a flat bottomed flask?
Flat bottom flasks (Erlenmeyer and Florence flasks) are used for heating all the time.

You need a heat source, a condensing tube and flasks.
What processes of heat transfer are affected with thermos flasks?

What are the difference between td and tc pipets?
The labels TC and TD mean "to contain" and "to dispense" respectively. What this means is that glassware can either be calibrated for the purpose of containing a solution or for the purpose of transferring and dispensing a solution. Most flasks will be labeled TC while most pipets and burets will be labeled TD.
Why are volumetric flasks not put into the drying oven?
Because your teacher will probably have a fit. In the old days, you could put volumetric flasks into a drying oven, but you couldn't take volumetric flasks out of a drying oven... the heat would warp the glass slightly and introduce error into the calibration mark, so the flasks would not actually be volumetric anymore. However, borosilicate glass (Pyrex and the like) is much less heat-sensitive, and studies have shown that there's no discernable change in the capacity of borosilicate flasks even after repeated exposure to temperatures considerably higher than those normally found in a drying oven. So, aside from the aforementioned fit, there's no real reason not to do it as long as you're using borosilicate glass flasks.
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.

Where can someone get cheap flasks?
A person can get cheap flasks at the nearby stores such as Wal-Mart, Target, K-Mart, and other stores like Staples. A person can also research where to find flasks and get them.
