Copper(II) oxide, CuO, can be used.
What is air but a mixture of gasses? Nitrogen, oxygen, helium and a little argon.
It depends on what you're talking about. If you mean just the drink (no carbon dioxide) it's a solution because the substances in it can't really be separated. However, if you count the little fizzy bubbles, it then becomes a mechanical mixture because the liquid and gas can easily be separated.
just get a gravel, sand, and cement and then mix it with a little amount of water.
A Nitrogen molecule has a triple bond.So high amount of energy is needed to break down this bond.Bond dissociates naturally in occasions like lightning.So Nitrogen's reactivity is very low.Nitrogen has a little bit high molecular mass.So it has a high escape velocity.As a result of those Nitrogen remains in atmosphere in huge amount.
Yes
At normal temperatures found on Earth, air (a mixture of mostly nitrogen and oxygen) is a gas. Reducing the temperature of air will cause its constituent gases to liquefy (at various temperatures).
The best reason I can think of for why we believe that air is a mixture is that freezing air slowly yields different liquids at different temperatures. Liquid nitrogen has a different boiling point than liquid oxygen. They also freeze at different temperatures. If air were only 1 compound, then air in its entirety would have a single boiling point and a single freezing point.
The physical property of oxygen that enables it to be separated from the other components of air is its higher boiling point compared to nitrogen. This difference in boiling points allows for distillation or fractional distillation processes to separate oxygen from the air mixture.
It's when there's a little less fuel for the amount of air than the ideal condition.
no Yes it can.Due to the little holes in the filter paper. The holes send through the clean water into a beaker. No it won't. Look at the mixture of oil, water and food coloring.
It is a mixture, since solutions are clear. In solutions, the solute is the substance that is dissolved and mud in water does not dissolve. Muddy water is not a solution, it is a mixture because u can separate mud from water.
"Neon can be recovered from large nitrogen plants as well as multi-product air separation units. Krypton and Xenon have higher boiling points than oxygen, from which they can be separated by distillation in air separation plants. When these products are recovered from ammonia plant purge gas, the neon must be separated from hydrogen and nitrogen, and the krypton and xenon from methane.

Annual world production is around 1 ton. help a little at least. Good luck! ~Starburstia~
