HOW DO YOU SEPARATE H20 into hydrogen and oxygen?

"The well developed way of splitting water is by electrolysis. If fossil fuels, e.g. coal, oil or natural gas, are used to generate the electricity, there is no advantage over using the fossil fuels directly. Indeed you still get all the CO2, and there is a considerable loss of energy. Therefore, the large scale use of hydrogen depends on using either nuclear or solar electricity. In both the nuclear and solar cases, there are possible but undeveloped technologies that don't use electricity as an intermediate form of energy. [2003 September: There is a thermochemical process for splitting water that is claimed to be twice as efficient as elactrolysis. Here's an article on the sulfur-iodine cycle by Ken Schultz of General Atomic given at a Stanford University Global Climate and Energy sponsored meeting in 2003 April. To get good efficiency it requires reactors operating at a higher termperature (950 C) than present power reactors. Schultz's article also discusses solar thermal production of hydrogen. (There are also proposals to combine getting heat for houses and chemical processes and electrolysis with some saving of energy.)"\n\n"Set up an electrolysis apparatus to use solar energy to separate water into hydrogen and oxygen gases."\n\n"Regenerative - Currently being researched by NASA; closed loop form of power generation that uses solar energy to separate water into hydrogen and oxygen."\n\n"Researchers are also exploring the molten carbonate fuel cell, which can generate energy from coal-based fuels, and regenerative fuel cells, which use solar energy to separate water into hydrogen and oxygen."

The electrolysis process seperates water into hydrogen and oxygen, and it requires a great deal of energy. Loosely speaking, if you reversed the process, you could get energy out of it, which, I believe, is what hydrogen fuel cell vehicles do.\n\nHowever, a system like this has to take seperated hydrogen and oxygen as input, not water. The reason is that the vehicle would have to run the electrolysis process forward, and then in reverse! The laws of thermodynamics tell us that energy will always be lost, and never gained, by such a process.\n\nHydrogen fuel cell vehicles would have to be supported by large electrical plants (nuclear preferably) which powered factories that ran the first part of the process. Energy is still lost in the end, but the overall cycle is highly efficient.

trying to be a smart ass huh? well if you are not then here is the answer.\n\n"FREE" hydrogen and "FREE" oxygen mixed together is highly explosive, however a Hydrogen Oxygen "COMPOUND"(water) is not.

Simple and complex techniques exist to split such atoms.  For example a high powered laser can split that into h2 and 0.\n\n:) That's a very simple way of doing it.\n\nElectrolosis also splits water into hydrogen and oxygen.

ex: 2 hydrogen atoms and 1 oxygen atom combine to create 1 molecule of H20(a chemical change).

Although some have talked about this, there are a lot of technical and practical questions to answer before this can happen. For example:\n\nWhat energy are you going to use to separate water into oxygen and hydrogen? \n\nHow are you going to store the hydrogen safely and dispense it? \n\nHow are you going to transport the hydrogeon?\n\nWill you keep the hydrogen liquid so it will not take up much room? \n\nHow will you keep the hydrogen liquid from warming up ? \n\nHow will you prevent terrible fires and explosions from accidents?\n\nWill you produce less pollution by using hydrogen, or more, given that you are having to use energy to create it? \n\nHow will you make the transition from petrochemical fuels to hydrogen fuels?\n\nWho is going to pay for this transition?\n\nHow are you going to build the very expensive infrastructure?\n\nProbably lots more questions too. Those are enough to start with, however.

Hydrogen and oxygen.  together, it's water.  Seperately, one is a powerful oxidizer that can, at high doses, attach tissues and potentially cause cancer; the other a powerful explosive gas.

H2SO4 - H20 = SO3\n\nAnyhydride is the removal of the atoms of water, therefore leaving Sulphur Trioxide.

You'll have to explain what you mean by solar hydrogen panels. \n\nThe most common is through steam reforming which must be done on an industrial scale. Steam reforming uses separates hydrogen from the carbon components in methane and methanol on catalytic surfaces. Something that would be impossible outside a very advanced lab or factory.\n\nThe second most common method of extracting hydrogen from water is through electrolysis where voltage is applied to water.  You can make some at home quite easily and safely. You just need a 9V battery, some wire, and the cleanest water you can find.\n\nYou simply place the two wires in the water while connected to the battery and hydrogen bubbles start forming. Use salt to make it more efficient.\n\nSee this site for more info.\nhttp://www.theodoregray.com/PeriodicTable/Stories/001.1/

Hi,, hydrogen, oxygen, and nitrogen... \n\n good luck.....

New in Chemistry?????\n\nThere is no conversion of H2O in HHO.\nIt is simply way of writing a formula. HHO is wrong, it is HOH.\n\nActually Oxygen has two separate bonds with two different atoms of Hydrogen so it is written as H-O-H.\n\nWhen H-O-H is broken it usually converts to H+ and OH-

yes! liquid oxygen and liquid hydrogen.  mix them together, light a match and stand back.

Yes you could. Free hydrogen (H2) is rare in the atmosphere though, so you would have to buy industrially obtained hydrogen (which mostly comes from natural gas) which is expensive so its always cheaper to drill a water well or something. But yes, if you want to combine oxygen and hydrogen, and light it with a match, you will get water. Good luck trying to contain it after it goes from gas to the combustion product of hydrogen and oxygen, which will be water vapor (steam).

H20 is hydrogen that has already burned. It can't burn a second time.  When burn hydrogen, the "ashes" is water. \n\nThere are two ways water puts out fires. One, it turns to steam which blocks out the oxygen the fire needs to burn. Two, in turning to steam, water absorbs a tremendous amount of heat. That cools the burning materials to a temperature below their flash point so the stop burning.

you'll have a mixture of hydrogen and oxygen
