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.
How does a gas respond when put in a jar?
It expands to fill the jar and takes the shape of it.
Do you have a sealed jar full of air if you put it in the freezer what happens to the gas pressure in the jar?
If you put a sealed jar full of air in the freezer, the gas pressure inside the jar will decrease. This occurs because the temperature of the gas drops, leading to a reduction in the kinetic energy of the air molecules, which results in fewer collisions with the jar's walls. According to Boyle's law, as the temperature decreases, the pressure also decreases, assuming the volume of the jar remains constant.
How would you capture hydrogen from a chemical reaction of an acid and a metal?
The hydrogen in such a reaction can effectively be collected using an apparatus called the gas jar. THis can be done by fitting the reaction flask with cork and a delivery tube running from the reaction flask to the gas jar. As the reaction proceed, the hydrogen evolved will be collected in the gas jar.
What would heating a glass jar do?
Increase the pressure of the gas inside
What is is someone who collects jars called?
A jar collector.
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.

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.
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.
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.
Bromine gas is put into 1 jar and then a gas jar of air is placed over it after a few minutes the bromine gas can be seen filling both gas jars why?
What has occured is a process called diffusion, which is the spreading of particles from a higher concentration to a lower concentration. The particles in any gas move quicly and in all directions and fill their container because there are no bonds between them. The jar with the bromine gas has a higher concentration of the gas particles, they move through the air particles to the jar with the lower concentration of bromine gas until they are dispersed evenly throughout the jar, hence the gas can be seen filling both jars. The same would happen with a clear gas but bromine is used for demonstration purposes as it has a colour and so the process can be seen clearly.
Give a reason why it is necessary to leave the gas jar undisturbed in a soil profile activity?
Leaving the gas jar undisturbed in a soil profile activity ensures that any gas released from the soil is accurately captured and measured. Disturbing the gas jar can lead to loss of gas or inaccurate results, affecting the analysis of the soil's gas composition.
One who collects coins is called?
A numismatist is someone who collects coins and/or medals a numismatist
What holds gas 2 words each 3 letters?
gas jar
