Usually when we think of oxygen, we think of the air we breathe. The air around us contains oxygen gas, as well as many other gases. If the air is cooled enough, it will change from a gas into a liquid or a solid.\n\nAir is made mostly of oxygen and nitrogen. To get nitrogen gas changed to a liquid, it must be cooled to minus 321 degrees Fahrenheit, which is minus 196 degrees Celsius. Oxygen turns into a liquid at a slightly higher temperature, minus 183 degrees Celsius. To get these gases down to such low temperatures, the air is compressed and cooled. When it is allowed to expand again, the temperature drops even further. By repeating this process many times, the air is eventually cooled to minus 312 degrees Fahrenheit. The liquid formed is a combination of oxygen and nitrogen.\n\nTo separate the oxygen, the liquid is warmed just enough for the nitrogen to turn back into a gas - leaving only the liquid oxygen.

Here's the o2 web site.\n\nhttp://www.o2.co.uk/\n\nLook around for what you need or Contact them if you need further help

WoW Dude! Hydrogen and oxygen BOTH in water! Now that is just so new-age and just today right? \nDamn Man! If you and I could just figure how to separate the two...\nSorry got lost in the thought! Please submit your picture to Ripley"s...

I heard that having ozone treatment is amazing for coldsores apparently they never come back, it was on This Morning quite a while a go and i took down the website.  Have a look, hope it helps!  Good luck!

Liquid oxygen is oxygen in liquid form. It is used in hospitals as a mix gas by anesthesiologists. The pure oxygen is mixed with other gases that put you to sleep because without oxygen you would die. It is liquid because they compress it (cool it) until it changes into a liquid state. It makes it possible to keep more oxygen in a smaller container. That means less trips for more o2. Some think it is used more for cryogenic storage but that is usually not the case at hospitals. It is highly flammable and not very safe for use as a storage medium. Liquid nitrogen is usually used for that. On a side note, the bottle you saw it stored in is just like a thermos you would use for coffee or a cold beverage. It is basically a big insulated bottle with a lot of plumbing in it.

The boiling point of oxygen is -183°C, or 90°K (-297°F).\n\nThe melting point of oxygen is -218.4°C, or 54.8°K  (-361.1°F)

Well if I remember this right...NASA was doing experiments a few years ago with rhubarb and pumpkin plants. The C02 oxygen exchange was the greatest. Also there was something about a genetically engineered algae they were trying out

nobody here has got it exactly right. \n\nhere's a link that will tell you everything you ever wanted to know about it (and more)  http://en.wikipedia.org/wiki/Liquid_breathing\n\nenjoy

Look at the acronym he uses -- hho.  What's another way to write that -- perhaps H2O -- which is water!\n\nThere have been many scams purporting to generate power by injecting water into a fuel supply, or a carburator, etc.  But they are SCAMS.  \n\nThe laws of thermodynamics make it impossible to get more energy out of a system than you put into it -- so you'd require more energy to electrolyze the water into hydrogen and oxygen than you could ever possibly get back by the recombination reaction, even in a perfectly designed system.

I think you should keep it simple yet smart. First get a piece of pure elemental Sodium and then let it drop on warm water. Afterwards explain how the chemical reaction released Sodium Oxide and Hydrogen Gas.

1) this one is already balanced for you!!\n\n2)Count the number of Mg and O on the right side, and count the number of Mg and O on the right side.  On the left, you have 2 O and 1 Mg, and on the right you have 1 Mg and 1 O.  To make the oxygen on both sides equal, you need to double the MgO.  Now on the left, you have 2 O and 1 Mg, and on the right, you have 2Mg and 2 O.  Now you need to multiply the Mg by two so the Mg on both sides is equal.  and you're done!!!! \n2Mg + 02 --> 2MgO\n\n3) On the left, you have 1 Zn, 1H, and 1 Cl.  on the right you have 1 Zn, 2Cl and 2H.  the Zn are balanced and you just need to multply the HCl on the left to balance the whole equ.\nZn + 2HCl --->ZnCl2 + H2\n\n4) On the left, you have 1 P and 2O, and on the left you have 4 P and 10 O. If you multiply the P on the right by 4, and the O on the right by 10, you have 4P and 10 O on both sides\n4P + 5O2 ---->P4O10\n\n5)  On the left, you have 1 Fe 2 Cl, and pn the left, you have 1 Fe and 3 Cl.  The easiest way to balance this is multiply the Cl on the right by the amount of the left one and vice versa. when you do that, you have 1 Fe and 6Cl on the right, and you have 2Fe and 6Cl on the left. To finish the equation, multiply the Fe by two.\n2Fe + 3Cl2---->2FeCl3\n\nVoila!  You have balanced 5 equations!\n\ni hope this was helpful!

Liquid hydrogen (fuel) and liquid oxygen (oxidizer) are used in many applications for rockets. The one that comes to mind is the Centaur upper stage on Atlas-Centaur and Titan-Centaur expendable launch vehicles launced by NASA.\n\nThe fuel and oxidizer, which are gases at normal atmospheric pressure, are compressed to liquids under high pressure and low temperatures.

There is a chemical called phosphorus that produces a faint glow when in contact with oxygen, but I wouldn't recommend it as its pure form is highly combustible.\n\nTheres also a naturally occuring chemical called luciferin. When digested by its enzyme, luciferase, it produces a glow.

It is quite possible to recycle oxygen and water for a station like the ISS. Great progress is being done in water recycling, they reuse the water we exhale and are working on reusing the water in urine. \n\nThe oxygen is trickier. The actual process is well known but the reactors needed are too energy hungry and may also be dangerous: they produce methane gas as an intermediate product. Using the moon and doing the work there would make more sense. There isn´t a lot of water there but oxygen is plentyful. It is the main component of lunar soil. Shipping all the waste from the ISS to the moon instead of dumping it and shipping oxygen and fresh water back makes more economic sense than permanently launch it from earth. \n\nThe waste would basically be sewage, CO2 (bound to lithiumhydroxide) and various wastes like plastic containers and food waste. As much water as possible would have been extracted from the waste. Water is mostly oxygen by weight and since there is plenty of oxygen it is a waste of energy. On the moon the plastic containers are cracked, turned into carbon and hydrogen as far as possible. Then you take lunar minerals like ilmenite (a slightly ferromagnetic iron-titanium oxide) and run a stream of hydrogen through it. Water is the result as the hydrogen reacts with oxygen in the mineral. You split the water into pure oxygen and hydrogen. You run the hydrogen through the mineral to get more water while you use the pure oxygen to incinerate all the other waste. You get even more co2 and water from this, which you use to extract more oxygen, and eventually you will end up with lots of oxygen and also metals like steel and titanium. (Biological processes aren´t used in the beginning as they are less reliant and predictable in space. All exhaust and ashes from the incineration is kept and stored as it will be used when biological waste digestors and food production are ready to be put into use.) You ship the oxygen to the ISS (along with fresh lithiumhydroxide canisters) to be turned into more carbon dioxide. We don´t want to ship CO2 (the oxygen) so a process where is reacts with hydrogen can be used. You get methane and water. The water is used aboard while the methane is shipped to the moon along with the other waste. By doing this the moon will become enriched with the volatiles (hydrogen, nitrogen, carbon) that are missing today.

basically you're talking about distilling water, which is a purification technique.  collect the water vapor and let it condense. the result is pure water.

the production of alcohol is an anoxic reaction, if oxygen is present alcohol isn't produced. This is usually achieved by putting the fermentation mixture in a sealed flask with a water stopper in the top, this allows the escape of CO2 produced in the fermentation but doesn't allow O2 in the air to dissolve in the water
