Does bromine diffuse faster in a vacuum?
Bromine diffuses slowly in the air because the motion of bromine particles is obstructed due to the collision with the moving air particles. But bromine diffuses very rapidly in a vacuum because in a vacuum there is no gas, and the motion of the particles of bromine gas is not obstructed by any other particle.
Does bromine diffuse in vacuum?
Bromine diffuses slowly in air because the motion of bromine particles is obstructed due to the collision with the moving air particles. But bromine diffuses very rapidly in vacuum because in vacuum there is no gas, and the motion of the particles of bromine gas is not obstructed by any other particle.
Which is heavier bromine Vapour or air?
Bromine gas is heavier than air due to its atomic weight. Being heavier it still floats in the air due to diffusion and collision between the particles of bromine and air molecules.
Is bromine a gas at STP?
Bromine is a liquid at STP, so this question is missing an assumed mass or volume. Its boiling point is 58.8∘C .
Why diffusion of bromine is faster in a vacuum?
Answer: Diffusion is the random movement of particles.In the diffusion process of bromine and air,the bromine particles continuously collide with the particles of air. But in vacuum there are no particles to collide. Hence bromine diffuses faster in vacuum than in air.
Which gas will diffuse faster bromine or chlorine?
Explain your answer. According to Graham’s diffusion Law, the rate of effusion or diffusion of a gas is inversely proportional to the square root of the molar mass of the gas. This is because lighter molecules diffuse faster than heavier molecules. Hence, Chlorine particles will diffuse faster than bromine particles.
How do gases diffuse in a vacuum?
Gases permeate through most materials, so gases present in the ambient air can permeate to vacuum chambers through the system walls. First, the gas dissolves in the solid and then it diffuses to the inner wall of the system. When the gas arrives at the inner surface, it desorbs to the vacuum volume.
Why diffusion of bromine is faster in vacuum than in air?
Diffusion is the random movement of particles.In the diffusion process of bromine and air,the bromine particles continuously collide with the particles of air. This slows down the diffusion rate. But in vacuum there are no particles to collide. Hence bromine diffuses faster in vacuum than in air.
Is bromine lighter than oxygen?
both air and bromine have the same density, air is heavier than bromine.
How is bromine extracted?
The crude bromine, containing water, chlorine and organic matter, is purified by distillation. The bromine in the solution is ‘stripped out’ with steam. The bromine is further purified by distillation, and then dried with concentrated sulfuric acid. About 95% of the bromine is recovered from the brine.
What is the density of bromine gas at STP?
7.14 g/L
The pressure is equal to 1 atm and the temperature is equal to 273.15 K at STP. The universal gas constant or R is equal to 0.082 L atm/ K. So, the density of bromine gas under the given condition is 7.14 g/L.
What is the difference between a gas and vapor?
Vapour is a substance that is a combination of gaseous and liquid phase in ordinary conditions. Gas is a substance that has a single thermodynamic state in ordinary conditions. Examples: Iodine exists in a solid form under ordinary conditions, but upon heating, it changes to the vapour form.
How are people exposed to bromine in the air?
Following the release of bromine into water, you could be exposed by drinking the contaminated water. If food becomes contaminated with bromine, you could be exposed by eating the contaminated food. Following release of bromine gas into the air, you could be exposed by breathing the fumes.
How big is the atomic mass of bromine?
Bromine is found in almond. Bromine is a chemical element with the symbol Br, an atomic number of 35, and an atomic mass of 79.
What kind of odor does bromine have in water?
Bromine is a dark reddish-brown fuming liquid with a pungent odor. Denser than water and soluble in water. Hence sinks in water. Toxic by inhalation. Accelerates the burning of combustible material.
Is the bromine in water toxic to humans?
Bromine is a dark reddish-brown fuming liquid with a pungent odor. Denser than water and soluble in water. Hence sinks in water. Toxic by inhalation.
