Liquid nitrogen is colder than liquid oxygen. You use the liquid nitrogen to chill the oxygen in the air and liquid oxygen will form. Liquid water and dry Ice (CO2) should also form due to their presence as well, but not in large quantity.
WARNING!! High concentrations of oxygen should be considered dangerous. When exposed to a small ignition source, it can cause flammable materials to combust much like an explosion, and will cause normally non flammable materials to burn readily. Human flesh burns better than wood after being exposed to 100% oxygen for a period of time. Please be careful.
Liquid Oxygen and Liquid Hydrogen are used as rocket fuel as it is the most effecient way to thrust rockets into space, Liquid Nitrogen is not transported into space.
The simple awnser is cool it. You can use liquid nitrogen to do this.
At room temperature: Oxygen & Nitrogen are gases, Carbon is solid, & Mercury is a liquid.
Cool the gases to a temperture between the boiling points of the two gases. Nitrgen condenses to a liquid at a higher temperaturte than oxygen. So liquid nitrogen is drawn off and gaseous oxygen remains.
Actually, what you breathe in is a mixture of nitrogen (~79%) and oxygen (~21%). It means that both of them (therefore oxygen, too) are in gaseous stat (not liquid).
No. The wind is composed of a small amount of water vapor and about 20% oxygen and about 80% nitrogen. The water vapor may freeze but the oxygen and the nitrogen cannot freeze at the temperature of liquid nitrogen. Oxygen has a much lower freezing point than liquid nitrogen and if the nitrogen were to be frozen, liquid nitrogen is not cold enough to freeze it...sort of like trying to make ice using cold water.
dry ice −56.4 °C and liquid nitrogen is −196 °C

Yes. Liquid nitrogen can contain liquid oxygen, or liquid argon. These are generally removed during the manufacturing process.
There are two reasons. First, liquid nitrogen is colder than liquid oxygen and thus more effective at flash freezing. Second, liquid oxygen is a fire hazard; it creates an atmosphere of pure oxygen that allows substances to burn more easily. Nitrogen does not support combustion.
By fractional distillation. Allow liquid air to get less cold. At around 77.4K, nitrogen will boil off while oxygen will remain liquid. The temperature will begin to rise again when all the nitrogen has boiled off.
Rockets typically use Liquid oxygen and liquid hydrogen for fuel. I suspect this is what you are asking. I know of no rocket that uses liquid nitrogen.
No, as nitrogen on its own does not support combustion. Combustion is technically an oxidation process (reaction of a chemical with oxygen) and without oxygen, combustion of any fuel would be impossible to achieve.If you are suggesting using nitrogen as a fuel, that is not viable as well since nitrogen is not highly combustible (otherwise air which is 23% oxygen and 75% nitrogen would permanently be combusting).Nitrogen storage would also be a problem since to store nitrogen as liquid, very high pressures are needed and liquid nitrogen is very cold (-190 Degrees C)

Liquid nitrogen is made by taking in air from the atmosphere and compressing and cooling it. Once it is cool enough, it forms a liquid. This liquid contains argon, oxygen and nitrogen. These elements are then separated and sold as a commodity. The temperature is the only difference.
