Hydrogen oxide
could i produce pure water with pure hydrogen and oxygen?

Not really... impossible without high temperatures, a platinum catalyst, high pressure vessel, sophisiticated electronic equipment and very expensive
precursors!

Not to mention the radioactivity released when H undergoes fusion into H2 needed for the H2O.

There's a chain of experiments which several scientists performed, I think I'm thinking of one of Faraday's lectures (ohh, the days
when experiments were allowed in class  ), goes something like generate oxygen and hydrogen from water, then ignite them in a (very heavy) glass container and
watch the water condense. Viola, reassembled.
H + H = H2 isn't fusion dude, it does have a lot of energy though!

For those of you who do not know this already, the combustion of H in O produces large amounts of a chemical known as dihyhrogen monoxide. For
background on this dangerous chemical, see this site.

LOL.
Alas! so hazardous, yet so useful. The implications of banning such a worthy reagent are terrible!
I think the site should mention that dihydrogen monoxide is actually the number one most used chemical, NOT sulfuric acid as some would say.

Um, yeah, I thought this was a joke thread, so I was following cyclonite4's lead on how "complicated" it is to make water.

All you need to make water from hydrogen and oxygen gasses is to mix the two together and ignite them. There is nothing more to it. To make sure you
use up all (or just about all) of your original gasses, use two parts hydrogen to one oxygen.
You may get some amounts of h202 (hydrogen peroxide) in doing so, but I doubt it. If your original gasses were very pure, then yes, your water will
turn out pure as well.
This reaction is very exothermic, and if it is done in a large enough amount, then it will definitely be very loud and most likely very dangerous.
However, small amounts are hardly a problem. Keep in mind you won't get very much water out of the reaction, and it will be in gas form due to
the energy created by the reaction.
Small amounts are fairly safe to handle
If your true purpose for this post was to find out a good way to make pure water, then you should be asking about that directly, and then go on to
suggest the reaction of hydrogen and oxygen. People here will answer only what they are asked, after all.
Finally, the best way to get pure hydrogen gas is with electrolysis. If you add salt to the water, it works faster but then you have chloride that
comes out into the gas, or something like that. Anyway, another way to get hydrogen is to put metal into an acid. Don't know how pure of hydrogen
you'll get from that.

Sodium carbonate or bicarbonate or an oxidized acid like 10-20% H2SO4 works well as electrolyte.

does anybody know what the ratio of hydrogen +oxygen gas to water is. and would i still get pure water if i burned hydrogen in air?

Your proposal is flawed, moose sniffer. I see you want to make DHMO. What you should do is obtain hydrogen peroxide (the higher concentration, the
better; around 70% should suffice, don't settle for the drugstore crap!) and dump something like manganese dioxide or lithium aluminum hydride
into it, thus forcing out the extra oxygen and giving you the Holy Grail hydrogen oxide!!!!!
sparky (~_~)
P.S. On a more serious note: you REAAALLLY have a long way to go, moose sniffer.

Yes sparkgap, that would work, perhaps too well . Let's hope he
doesn't take that to heart or we'll have one less forum member.
Anyways, if you want to make water, try using the 3% hydrogen peroxide with a miniscule amount of potassium permanganate, or even some potassium
iodide, heck, blood would work. That will break it down to oxygen, you can collect that. You can make the hydrogen with some zinc and dilute
hydrochloric acid (zinc in post 1982 pennies). If you had a eudiometer you could be a little more precise. Mix the two gases together and see what
happens! Now since nothing happened, carefully get a lit match on a stick and try again. There's your water and a nice little lesson on
activation energy

Yes, if i remember correct water (H2O) was first prepared by an electric "charge" in H2 and O2
