How can you get Oxygen Hydrogen Nitrogen Carbon Phosphorus and Sulfur as pure elements?
Oxygen and hydrogen can be obtained by electrolysis of water. Nitrogen by liquefying air,and phosphorus and sulphur by other chemical reactions. Search the internet you'll find it!!
What gas is obtained by fractional distillation?
Most of the gases in air, Nitrogen, Oxygen, Argon and others are obtained by fractional distillation of liquid air.
Is pure air an element compound solution or heterogeneous?
The pure nitrogen is a chemical element, gaseous at room temperature.
Does nitrogen weigh more than air?
No. Nitrogen is slightly less dens than air. The density of a gas is directly proportional to its molecular mass. Dry air is 78% nitrogen, 21% oxygen. Nitrogen has a molecular mass of 28 AMU. Oxygen has a molecular mass of 32 AMU. This makes air just a bit denser than pure nitrogen.
Is liquid nitrogen a pure or mixure substance?
Yes Nitrogen is a pure substance because pure substances are both compounds and elements. Nitrogen is an element.
Where is nitrogen found or obtained from?
== == Nitrogen is found in all living systems as part of the makeup of biological compounds. Nitrogen is obtained from the atmosphere by passing air over heated copper or iron. The oxygen is removed from the air, leaving nitrogen mixed with inert gases. Pure nitrogen is obtained by fractional distillation of liquid air; because liquid nitrogen has a lower boiling point than liquid oxygen, the nitrogen distills off first and can be collected.
Is N2 a pure substance or a solution?
Nitrogen (N) is a chemical element, not a solution; nitrogen can be obtained as a very pure gas.
What raw material is nitrogen obtained from?
Liquid Air
Can you mix air and nitrogen in tires?
Air is 78% nitrogen, and most tyres are inflated with air, so mixing pure nitrogen with air would not be a problem.
How do you find nitrogen percentage in air?
The percentage of nitrogen in pure, dry ,standard air is 78,084 % (by volume).
How can you get Oxygen Hydrogen Nitrogen Carbon Phosphorus and Sulfur as pure elements?
Oxygen and hydrogen can be obtained by electrolysis of water. Nitrogen by liquefying air,and phosphorus and sulphur by other chemical reactions. Search the internet you'll find it!!
What element is obtained from liquid air by fractional distillation?
Nitrogen
Is Air (Nitrogen and Oxygen) a pure substance?
Air is a mixture of gasses, about 78% nitrogen, 21% oxygen and then a dash of others. Nitrogen OTOH is one of the elements out of the Periodic Table, which I guess is what you mean with a pure substance.
What gases are found in pure air?
carbon, nitrogen and oxygen
What gas is obtained by fractional distillation?
Most of the gases in air, Nitrogen, Oxygen, Argon and others are obtained by fractional distillation of liquid air.
Is the air we breathe pure oxygen?
No. It is only about 21% oxygen. Air is about 78% nitrogen.
Is air or nitorgen a pure substance?
Air is a mixture of gasses, about 78% nitrogen, 21% oxygen and then a dash of others. Nitrogen OTOH is one of the elements out of the periodic table, which I guess is what you mean with a pure substance.
