How do you deal with the liquid mercury scattered in laboratory?
Set up a vacuum flask with flexible intake tubing long enough to reach the mercury spill. Use glass tubing on the inside of the flask to reach nearly to the bottom on the intake side. On the other side (the side connected to the vacuum source) make sure the glass tubing reaches just inside the flask, near the top, so that the mercury entering the flask will not simply be sucked into the vacuum source lines. Use a two-holed rubber stopper to accomplish all this. This will give you a mercury vacuum cleaner, so to speak. Use a regulator and be careful to use just enogh vacuum to lift the mercury into the flask.
What has one hole and can hold glass tubing?
A glass, beaker, flask, jar and anything else that has a hole on top.
Which theory did pasteur disprove by using boiled beef broth and a flask with s-shape tubing?
spontaneous generation
Why receiving flask supposed to be kept on ice during preparation of cyclohexene?
Cyclohexene is a volatile liquid Thus, the flask is cooled to reduce the degree of evaporation to a minimum
Which theory did pasteur disprove by using boiled beef broth an a flask with S-shaped tubing?
Pasteur disproved Theory of spontaneous generation. (Cells came from non-living things)

What stoppers a flask?
Normally cork or rubber is used as a stopper in a flask.
What can you use to secure a flask from falling?
A rubber band can be used to secure a flask from falling.
What are two factors that could slow the transfer of water from the reservoir flask to the receiving flask?
swelling in the pumps.
What is a rubber stopper used for in chemistry?
Rubber stoppers are widely used for the commercial, industrial and scientific markets. They are made from different types of rubber and available in various sizes and styles depending on applications.What are Rubber Stoppers used for?Possible uses of rubber stoppers are wide and varied such as :Mechanical StopBumpersVibration MountGrippersClampsSticky feet for platformFits into Test Tubes, Boiling FlaskPipe stoppersPaint masksTube plugsDoor stopperThe kind of rubber stopper used in chemical laboratories is a plug which fits into the top of a test tube or flask, often with a hole or holes bored in it for the insertion of a piece of glass tubing. They used to be made of cork but rubber is less likely to disintegrate and get into the contents of the flask or tube.
Why is cotton wool used to plug a flask instead of using a rubber bung?
A cotton wool is used to plug a flask instead of a rubber bung because a rubber bung doesn't allow any gas exchange between oxygen and carbon dioxide. A cotton wool will allow them to leave and enter the flask during an experiment.

A glass, beaker, flask, jar and anything else that has a hole on top.

What happens if the distillation flask is not securely attached to the distillation head?
If a flask is not well secured to the head, all the gas will run out of the distiller.
Why receiving flask supposed to be kept on ice during preparation of cyclohexene?
Cyclohexene is a volatile liquid Thus, the flask is cooled to reduce the degree of evaporation to a minimum
What reacts readily with acids such as hydrochloric?
Small amounts of chlorine gas can be made in the laboratory by putting concentrated hydrochloric acid in a flask with a side arm and rubber tubing attached. Manganese dioxide is then added and the flask stoppered. The reaction is not greatly exothermic. As chlorine is denser than air, it can be collected by placing the tube inside a flask where it will displace the air. Once full, the collecting flask can be stoppered.
