What is the hole in the rubber stopper for?
The hole in a rubber stopper is used to allow for the insertion of glass tubing or a thermometer into a container without disrupting the seal created by the stopper. This allows for measurements or additions to be made to the container while maintaining a closed system.
When magnesium reacts quickly with hydrochloric acis to produce hydrogen gas in a glass tube with a rubber stopper why would the rubber stopper burst of?
The reaction between magnesium and hydrochloric acid produces hydrogen gas, which builds up pressure inside the closed glass tube. If the pressure exceeds the strength of the rubber stopper, it will burst off to release the built-up pressure and prevent the glass tube from breaking due to the increased pressure.
Why are the tubes sealed with rubber stopper rather than left open?
To avoid loss of substances.
What happens to the number of revolutions of a rubber stopper as the radius of rotation decreases?
As the radius of rotation decreases, the number of revolutions of a rubber stopper increases. This is due to the conservation of angular momentum - with a smaller radius, the rotational speed must increase to maintain the same angular momentum.
What are the laboratory apparatus of rubber plug?
The main reason for a rubber stopper is to stop gas or liquid from coming out of the container. Rubber stoppers can also prevent contamination of samples by keeping the laboratory glassware safe.
Where can you buy a rubber stopper?

What is the volume of rubber stopper?
The volume of a rubber stopper can vary depending on its size and shape. To find the volume of a rubber stopper, you can use the formula for the volume of a cylinder or sphere, depending on the shape of the stopper. Measure the dimensions of the stopper and plug them into the appropriate formula to calculate the volume.
Would a rubber stopper float in water?
i don't know... That's why I'm asking you. soo.. Does a rubber stopper float in water?
Is the density of rubber stopper is denser than the density of water?
No, the density of a rubber stopper is less than the density of water. Rubber has a lower density compared to water, so a rubber stopper would float on water.
When a rubber stopper has a mass of 8.46g was immersed in a graduated cylinder containing 25 ml of water the water rose to 30.9 ml Calculate the densityof the rubber stopper?
The volume of the stopper can be calculated by subtracting the initial volume of the water from the final volume. In this case, the volume of the rubber stopper would be 30.9 ml - 25 ml = 5.9 ml. Now, divide the mass of the rubber stopper (8.46 g) by its volume (5.9 ml) to find its density. Density = Mass/Volume, so the density of the rubber stopper would be 8.46g / 5.9ml = 1.43 g/ml.
What is the average life expectancy of a rubber stopper?
This is very variable and depends on: - type of rubber - temperature - pressure on the stopper - the liquid in contact - other conditions of use
What is the use of rubber stopper in laboratory apparatus?
pantakip.
What is the use of rubber stopper's laboratory apparatus?

Why must KClO3-MnO2 mixture be kept away from rubber stopper?
KCIO3-MNO2 cannot comes in contact with the rubber stopper otherwise, or a severe explosion may result.

If you put water mercury mineral oil a cork a rubber stopper and lead in a graduated cylinder in what order would they be in from top to bottom?
From top to bottom, the order would be: cork, rubber stopper, mineral oil, water, mercury, and lead. This is based on the densities of the substances, with cork being the least dense and lead being the most dense.
