A gas jar is used in microbiology. A flame is lit in the airtight jar which starts using up the oxygen in the jar and producing carbon dioxide. This creates an environment that is lower in oxygen than the normal atmosphere and creates a perfect environment for microaerophilic microbes which need a low concentration of oxygen in order to grow. It can also make fire...

Why chlorine is collected in jar?
Chlorine gas is collected in a jar because it is a highly reactive and toxic gas that can be harmful if released into the environment. Collecting it in a jar allows for safe storage and transportation of the gas for various industrial, chemical, and laboratory applications.
What is the use of a beehive shelf in chemistry labs?
A beehive shelf is used in chemistry labs to evenly heat glassware during experiments. It allows for better control of temperature distribution, reducing the risk of uneven heating and potential thermal stress on the glassware.
Why does brown fumes of bromine vapour spread through a covered gas jar?
The brown fumes of bromine vapor spread through a covered gas jar because bromine is highly volatile and readily evaporates into the gas phase, filling the jar with its vapors. The color of the fumes is due to the absorption of light by bromine molecules, giving it a distinctive brown color.
A gas jar containing air is placed upside down on a gas jar of bromine vapour.It is observed that after some time the gas jar containin air also becomes reddish brown. Name the process involved?
The process involved is diffusion. Diffusion is the passive movement of particles from an area of higher concentration to an area of lower concentration. In this case, the bromine vapour diffuses into the gas jar containing air, resulting in the air also turning reddish brown due to the presence of bromine.
Why a candle brought near the mouth of a jar containing hydrogen gas starts burning but is extinguished when pushed inside the jar?
When the candle is brought near the mouth of the jar containing hydrogen gas, the hydrogen gas reacts with oxygen in the air to produce water vapor and heat, allowing the candle to burn. However, when the candle is pushed inside the jar, the available oxygen is quickly used up by the candle flame, leading to oxygen depletion and eventual extinguishment of the flame.
Liquid bromine placed in a gas jar for one hour will diffuse throughtout the jar. Explain what happens to the liquid bromine in terms of particles?
senior chemistry textbook? im on that question!
What is the jar called that collects a gas?
Glass lids are slid under the gas jar when gases are being collecting. This is so the water vapor is collected.
Stranger gas in chemistry?
The xenon gas in Chemistry is what is referred to as the stranger gas in Chemistry.
in one of the gas jars the gas goes out immediately. name the gas in the jar?
If the gas jar is standing with its opening to the top, then the escaping gas is Hydrogen. If the gas jar is being held upside down ( opening to the bottom), then the escaping gas is carbon dioxide.
What method can you use to understand gas questions in chemistry?
increase the pressure on it
What is it necessary to have a hot nicrome wire in the gas jar?
A hot nichrome wire in a gas jar is necessary for conducting the auto-ignition test of a gas. It is used to ignite the gas in the jar to see if it will burn by itself. If the gas ignites, it indicates that the gas is flammable.
What is chemistry laboratory apparatus gas jar and its use?
there are several. a bell jar is used to demonstrate how removing air from around a bell prevents us from being able to hear its sound. the other kind that i can think of is a beaker, which is used to mix ingredients. it has measuring markings and a pouring lip, both of which are very useful when doing chemistry. it's made of glass because glass doesn't react to anything except extreme heat.
How does a gas respond when put in a jar?
It expands to fill the jar and takes the shape of it.
Why ammonia gas is collected in an inverted gas jar?
Ammonia gas is collected in an inverted gas jar to take advantage of its lower density compared to air. This allows the gas to displace the air in the jar and fill it completely, ensuring an accurate measurement of the gas volume. Additionally, collecting the gas in an inverted jar prevents any leakage or loss of the gas during the collection process. Finally, the inverted jar setup also minimizes the risk of the gas coming into contact with any moisture or impurities present in the surrounding environment, ensuring the purity of the collected gas sample.
Which jar would have more gas if each jar contained NH SO O N?
This depends on the volume and pressure of gas.
What is a beehive shelf?
It supports the test tube above it. Maria
