Why wouldn't it be sensible to put an ice cube in a vacuum flask?
When water freezes becoming ice it expands. In a vacuum flask as ice melts it will contract. This will cause the flask to crack.
If a chemical reaction produces a gas how can that gas be captured in a test tube?
The flask should contain the reactants, and a bung should be put in the top of the flask. a tube should lead to a gas syringe.
What is flat bottom flask?
A flat bottom flask would be an Ehrlemeyer flask, which is used quite a lot by chemists.anf
Suppose the scientist had put one type of gravy in the flask he left open and another in the flask he sealed would this be a well-designed controlled experiment?
Yes, because you'll find out if all gravy has the same reaction.
Gas is contained in a 125mL flask The actual volume of the flask is 131.5mL What is the volume of the flask in L?
Volume of the flask = 131.5 mL - 125 mL = 6.5 mL = 0.0065 L
How does a erlenmyer flask function?
"Function?" It's a flask. You put stuff in it. There's not a whole lot of functioning involved.

Why is it acceptable to add water to the titration flask?
Once you have measured out your sample and transferred it to your flask, the absolute amount (moles) of sample is fixed. Adding water to the flask will change the concentration in the flask, titrating also adds volume to the flask as well as reacting with the sample. However, the number of molecules of sample you put into the flask will not change by simply diluting it with water.
Do you have to put a flask in the fridge?
That depends on whats in the flask. Most alcohol is safe with out being refrigerated. But if the bottle says refrigerate after opening, then yes.
What you can do with a small flask that is intended for alcohol besides put alcohol in it?
nothing
If you put yeast and sugar in a flask without water what would you put in a flask for yeast to break down sugar?
Yes it can feed on sugar substitutes Yes it can feed on sugar substitutes Yes it can feed on sugar substitutes
What uses does a Erlenmeyer flask have?
An Erlenmeyer flask, commonly known as a conical flask or E-flask, is a widely used type of laboratory flask which features a flat base, a conical body, and a cylindrical neck. The flask is named after the German chemist Emil Erlenmeyer, who created it in 1861. Because the bottom is flat it can stand by itself as opposed to spherical bottom flasks which are also common.The flat bottom makes it easy to put on a stirring device which rotates a magnet in the flask.
What is measuring flask?
measuring flask is a measuring flask
Whats the difference between an Erlenmeyer flask and a Florence flask?
What is the function of the erlenmeyer flask?
The Erlenmeyer flask was named after its creator Emil Erlenmeyer, who was a German chemist. It is a flat bottomed cone-shaped container that has a tapered neck so that a person can hold it, put a stopper on it or attach a clamp with it. This flask is used to measure, mix, and store liquid.
What change in the water level occurs when you hold Erlenmeyer flask over a candle in a pan of water?
When you put a flask over the candle in a pan of water, the water in the pan starts to slowly rise inside the flask, and as the water slowly starts to rise, the candle slowly burns out.
If a chemical reaction produces a gas how can that gas be captured in a test tube?
The flask should contain the reactants, and a bung should be put in the top of the flask. a tube should lead to a gas syringe.
