What is the product of burning hydrogen? Smoke? Hydrocarbons? Or nothing? Thanks!
burning something is combining a fuel with oxygen. If you burn a hydrocarbon, you get water (hydrogen and oxygen) and carbon dioxide (carbon and oxygen). If you burn hydrogen gas (H2) then you get 2 H2 + O2 --> 2 H20. H20 is ...water...and you have a balanced equation, so there are no other products. Homework? Since it is exothermic, and the output is water, you are likely to end up with hot...water...or steam :)

so if hydrogen justs burns i still get steam? (not homework, just a project.)
Sure does -- Like they say, if you get air 'hot' in any reaction, its not just oxygen -- its got a bunch of nitrogen, neon, xenon, and other fun gasses -- most of them don't react, because the hydrogen and oxygen are really happy to mingle, but a few do - thus you end up with trace amounts of other stuff. Similarly, if you burn propane in a controlled setting you get ideally: (C3H8 + 5 O2 >> 4 H2O + 3 CO2 + heat). If you do it in air you get nitrogen (N2) forming a few extra chemicals...
Actully im going to vacuum out all the air in a tank and then fill the tank 1/4 full of hydrogen and than make a spark in there. What will it produce?
Assuming there is also some oxygen in there: an explosion.
Are you sure that's not homework?
ya, its a project for a fusion reactor. (plus it still summer) :P
Nothing: It needs oxygen. Hydrogen doesn't burn without it. Anything more than 5% hydrogen in air will explode with a spark ignition.
. Yep. In a "perfect" reaction 2H2 + O2 -> 2H2O + heat . As steveastrouk points out, in the real world, there will be other components, but water will be the main one.
Uh, mostly HEAT.
The name is derived from the Greek hudro meaning water, and -gen also from the Greek genes meaning to be born / become. Hence Hydrogen means "water-creator". L
Except if you burn in air, you get some nitrous compounds too apparently.
