No, only those that do not dissolve in water, or they will dissolve in the water rather than bubble through it to be collected. Examples of gases that can be collected over water include:- Hydrogen, nitrogen, oxygen (only slightly soluble), methane, carbon monoxide. Examples of gases that can just be collected over water (quie soluble - so much will be dissolved in the water as well):- Nitrogen dioxide, carbon dioxide, chlorine Examples of gases that are too soluble to be collected over water:- hydrogen chloride, ammonia (which is the most soluble of all gases) Both of these gases are collected by displacement of air - hydrogen chloride by the gas jar being held as in a glass - with the base on the table - because it is heavier than air (chlorine and carbod dioxide can be collected like this too) and and ammonia by the gas jar being held upside down to trap the ammonia (as it is lighter than air).

∙ 13y agoMany gas samples are not pure but consist of mixtures of ggases. The air in our atmosphere, for example, is a mixture containing 78% nitrogen, 21% oxygen, 0.9% argon,0.04% carbon dioxide, and a few other gases in smaller amounts. So the answer is No it can't be pure gas.

Some gases are slightly soluble in water and thus it is not a good idea to collect them over water.

Why is it helpful for a gas collection tube to be dry?
1. Gas in the tube may diffuse into the water droplets in the tube. 2. It may affect the volume count in the collection tube. 3. Some substances are sensitive to water and may give different results when water is present
Why do bubbles form in filtered water?
Non-polar gas molecules such as nitrogen and oxygen, which make up around 98% of the air, are not very soluble in water. There are two possible reasons why a standing glass of water will form bubbles if left over time. If you pour a glass of water you mix in additional gas to it which as the water / gas mixture returns to equilibrium, starts leaving solution (imagine oil sitting on water, stirring the two, and then watching the two separate again, the air above the water surface is like the oil in this case). Also as the temperature of water rises, the gas solubility falls and so they start to form bubbles out of solution. Water out of a tap may be cooler than the room. As the water warms up gas solubility falls, the equilibrium shifts, and gas and water start to separate.
When calcium metal is added to water the gas evolved doesn't catch fireBut the same gas evolved on adding sodium metal to watar catches firewhy it so?
Calcium reacts slowly with water and the evolved gas is converted in to H2 gas, while Na reacts fast with water and produces atomic hydrogen in a short time which may catch the fire.
What is sodium's reaction with cold water?
There will be a release of hydrogen gas & heat. Possible explosion or fire may follow.
Is steam water a gas?
steam is a gas
When is francium a gas?
At a temperature over 677 0C francium may be a gas.
Can pure water be extracted from skim milk?
Yes. The water may be boiled off or evaporated by heating in the usual manner, and then collected on glassware.
What is a liquid or a gas?
Water may be solid (ice), a liquid (water) or a gas (water vapour - or steam).The form it adopts depends on the ambient pressure and temperature.
As water moves through the water cycle it may become?
Solid, liquid, or gas.
What is crude gas?
Generally we refer to oil from a well as crude oil, but we referred to gas as produced gas. Most oil wells produce some gas. Natural gas from a well may require processing to remove contaminants and water. Natural gas from a well may require processing to remove contaminants and water.
How many gallons of water are in a gallon of gas?
Should the gas in question be water vapour then there is one gallon of water. (In gaseous form) Should the gas be anything else then it is possible that there may be some contamination. How much of that is water depends on the amount of contamination.

What are ways information can be collected without the owner's authority?
Information may be collected from the internet
Are data that was collected for another purpose and was already collected?
Data that is collected may have been collected previously for some reason, or it might have been collected recently. Data is usually collected to show statistics or information about something specific.
What liquid becomes a gas at 100 degrees celsius?
Water will become a gas at approximately that temperature (the temperature may vary, depending mainly on the pressure).
Why is water vapor called a variable gas?
There may not be as much water in one place than another.
What is the definition for collected funds?
Collected funds in banking are funds collected by the depository bank. These may be checks or drafts paid by the drawee bank.
