What else can I help you with?
Can oxygen be collected by the downward displacement of water?
Hydrogen can be collected by the downward displacement of water because of two reasons: it is less dense than water, and so rises to the surface, and it is not very soluble in water, and so nearly all the gas can be collected because very little is dissolved in the water.
What percentage of hydrogen is lighter than air?
100% of hydrogen is lighter than air
Helium hydrogen and air are in this state of matter?
Helium, hydrogen, and air are gases.
What kind of gas is in air bubble?
it is not gas it is just air
How much does ac decrease humidity?
Air conditioning decreases humidity by removing moisture from the air as it passes over the cooling coils. The condensed moisture is collected and drained, resulting in a decrease in humidity levels in the air that is circulated back into the room.
Why hydrogen cant be collected by the downward displacement of air?
Hydrogen is lighter than air, which is why it rises upwards in the atmosphere. When collected by the downward displacement of air, the denser air prevents the lighter hydrogen from being fully collected as it continues to rise. This method is more effective for gases that are denser than air.
Can you collect hydrogen gas over water?
Yes, hydrogen gas can be collected over water by displacing the water in a container with the gas. Hydrogen is less dense than air so it will displace the water, allowing the gas to be collected in the container while the water is pushed out.
What happened when the splint was brought to the mouth of the first bottle of hydrogen collected?
When the splint was brought to the mouth of the first bottle of hydrogen collected, the hydrogen gas ignited with a pop sound, indicating that hydrogen is a highly flammable gas. This reaction is due to the combination of hydrogen gas with oxygen in the air, creating water vapor.
Which gas may be collected over water?
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).
Why hydrogen gas collected by upward delivery?
Because hydrogen gas is less dense than air(mostly nitrogen and oxygen), and the less dense gas flows to go above the more dense(and escape the atmosphere).
Why some gases do not being collected by over water method?
because they are soluble in water and are denser than air
Why is ammonia collected by upward delivery and not over water?
Ammonia is collected by upward delivery because it is lighter than air and will rise through the apparatus. Collecting it over water can be problematic as ammonia can dissolve in water, forming ammonium hydroxide, thus contaminating the collected gas.
How can you make water from hydrogen hydrogen from water?
Yes. You cannot get water from hydrogen alone. You need oxygen. Since oxygen is a part of the atmosphere, simply burning hydrogen in air will give you water vapor. Passing an electric current through water will split it back into hydrogen and oxygen.
Where do get hydrogen from?
Hydrogen is in atmosphere.We get it from air.
Can oxygen be collected by the downward displacement of water?
Hydrogen can be collected by the downward displacement of water because of two reasons: it is less dense than water, and so rises to the surface, and it is not very soluble in water, and so nearly all the gas can be collected because very little is dissolved in the water.
Why is carbon dioxide collected by downwards delivery?
Carbon dioxide (CO2) is collected by downwards delivery because it is heavier than air. Almost all of our atmosphere is nitrogen (molecular mass = 28) and oxygen (molecular mass = 32), but CO2 has a molecular mass of 40.
Can hydrogen and air mix?
Yes, hydrogen and air can mix. However, hydrogen is highly flammable and when mixed with air in certain concentrations, it can form an explosive mixture. This is why caution is needed when handling and storing hydrogen in the presence of air.
