What else can I help you with?
What is over 99 percent of the atmosphere in pure dry air composed of?
Over 99 percent of the atmosphere in pure dry air is composed of nitrogen and oxygen, with nitrogen making up about 78 percent and oxygen around 21 percent. The remaining 1 percent is made up of trace gases such as argon, carbon dioxide, and neon.
Is Nitrogen and oxygen a homogeneous mixture?
No, nitrogen and oxygen are not a homogeneous mixture. They are two separate gases that can exist in the air as a uniform mixture.
What is the approximate mole fraction of nitrogen and oxygen in the atmosphere combined?
The approximate mole fraction of nitrogen in the atmosphere is about 0.7808, and the approximate mole fraction of oxygen is about 0.2095. When combined, the mole fraction of nitrogen and oxygen in the atmosphere is approximately 0.9903.
What would be the solute 80 percent Nitrogen 20 percent Oxygen?
In this case, the solute would be nitrogen since it is the substance that is present in the larger proportion (80%) compared to oxygen (20%). The solvent would be the medium in which these substances are dissolved, such as air or a gas mixture.
Is air mostly oxygen and nitrogen a mixture or compound?
Air is mostly a mixture of gases, primarily nitrogen and oxygen. Nitrogen makes up about 78% of air, while oxygen makes up about 21%. These gases are not chemically bonded and can be separated from each other.
Is a bottle of 30 percent oxygen gas and 70 percent nitrogen a homogeneous mixture?
Yes
The air you breathe is made of 21 percent oxygen and 78 percent nitrogen The oxygen in air is the?
It's the oxygen. Since oxygen doesn't dissolve into nitrogen - air is a mixture, not a solution - you can't call it the solute and the nitrogen the solvent, which may have been the answer you thought you were going to get.
Is Nitrogen and oxygen a homogeneous mixture?
No, nitrogen and oxygen are not a homogeneous mixture. They are two separate gases that can exist in the air as a uniform mixture.
What is the approximate mole fraction of nitrogen and oxygen in the atmosphere combined?
The approximate mole fraction of nitrogen in the atmosphere is about 0.7808, and the approximate mole fraction of oxygen is about 0.2095. When combined, the mole fraction of nitrogen and oxygen in the atmosphere is approximately 0.9903.
Is nitrogen monoxide a mixture?
No, it is a compound of the elements nitrogen and oxygen.
How may air best be described?
A mixture of nitrogen (80percent) and oxygen (20 percent)
What are two compounds that are formed when nitrogen combine with oxygen?
Nitrogen oxide can refer to a binary compound of oxygen and nitrogen, or a mixture of such compounds.
When 99 percent of the atmosphere is made up of either oxygen or?
The percentage of atmospheric gases are:- 79% ; Nitrogen (N2) 20% ; Oxygen (O2) 1% ; ALL other gases, which includes , Carbon Dioxide, Water vapour, The Noble Gases, Sulphur dioxide, Ammonia, Ozone(an allotrope of oxygen) and nitrogen oxides.
Is oxygen a mixture or a compound?
Neither. Oxygen is an element. In the air it forms a mixture with nitrogen, carbon dioxide, etc.
Why is oxygen 21 percent and nitrogen 78 percent?
This is the composition of the air.
What is the air around us?
A mixture of nitrogen and oxygen, mostly.
What would be the solute 80 percent Nitrogen 20 percent Oxygen?
In this case, the solute would be nitrogen since it is the substance that is present in the larger proportion (80%) compared to oxygen (20%). The solvent would be the medium in which these substances are dissolved, such as air or a gas mixture.
