what is hydrogen used for?

Question

could you seperate the dioxide from the hydrogen in water ( i am not a scientist so simple answers please)

if you can why do they not invent something for deep sea divers and people on submarines to use that converts the sea water so they have unlimited amounts of oxygen without re survacing

i thought about this in the middle of the night and i havent stopped thinking about it since

the reason i asked what hydrogen is used for is because it was seperated from the water then i take it it would be a wasted by product wouldnt it

thank you for your answers

Answer 1

Nuclear powered submarines all have what is called an oxygen generator. It uses electrolysis of water to produce hydrogen and oxygen. The hydrogen is discharged overboard and the oxygen is put in a pressurized oxygen bank (bottles) for immediate or later use while submerged.

It takes lot of power to run a generator like this, so it is only practical for submarines and not small submersibles or scuba divers.

Answer 2

Hydrogen is used in the production of ammonia, for many reduction reactions, as a fuel and many other applications.

Yes, you can separate the oxygen from hydrogen in water and this can be done by electrolysis.

They have indeed invented something for people on submarines to use that converts the sea water so they have unlimited amounts of oxygen without re surfacing. I believe that the limitation for a nuclear sumbarine is the amount of food needed for the sailors, not the air supply.

I guess that hydrogen produced by a submarine would just be bubbled away to waste, but on land hydrogen is very useful indeed. Aeroplanes have been built that use liquid hydrogen as a fuel and these could be the future when the oil starts to run out. Hydrogen is a very environmentally friendly fuel - it produces no CO2, CO or soot when burnt, only water and it can be produced using wave, wind or solar energy etc.

Answer 3

Water can be separated into hydrogen and oxygen. One of the simplests ways to do so is electrolysis (passing an electric current through it).

There are a few things that need to be in place before it can happen though,

1) the water needs to be made conductive (pure water is not very conductive), meaning there has to be something added to it (usually a strong acid/base or a salt) to allow the current (DC) to flow

and 2) This process takes energy, so there has to be an energy source available (and realize that the process isn't 100% efficient, so there will also be conversion losses)

Water electrolysis has been used on space shuttles, to provide astronauts with breathable air, and the hydrogen can be used as fuel (either in combustion engines or fuel cells). I assume this has also been done on submarines...

Very intuitive question :)

Answer 4

Hydrogen could be used for fueling futur automobiles

now as for seperating them

Electrolis which is basicly in simple words

sticking to metal sticks in the water and adding positiv(DC+) to one stick and negative ( DC-) to the other

and you could depending on the power you guive to the poles, seperate the H from the H2O meaning you could extract hydrogen from the water cells

as for why they didnt do this for divers :

Electrolis is long process requiring alot of current impossible to electroliss an entire water Mass such as ocean river or lake

so the yhave rebreathers instead wch take the carbon dioxide
CO2 out of your mouth and filthers it to become O2 again so you can breath

so basicly they would never be able to send divers without nothing to help them breath in the water unless humans evolve and grow guils like a fish as to breath


and to answer the other part

HYDROGEN = FUTUR GAS FOR CARS

Answer 5

Mostly hydrogen fuels stars.

Yes you can remove the dioxide from water and make hydrogen and oxygen.

They can create under sea habitats that a self sustaining. Submarines could be made to produce oxygen but what would be the point? Subs already stay under for months at a time.

Answer 6

i'd placed my bets on battery / electric powered vehicles before gas cells for here 2 motives. a million) Hydrogen gas cellular tech is costly. i'm doubtful as to "why", however the superb gas cellular tech available makes use of platinum. would as properly decide a thank you to make gas out of bald eagle feathers and faberge eggs. 2) Hydrogen isn't certainly occuring. meaning we ought to spend power to offer, shop, and transport hydrogen. yet another person reported cellular autos are 40 5% helpful mutually as ICE autos are sixteen%. by way of fact the cells want hydrogen, that ought to signify hydrogen production is any below sixteen%, we are as undesirable or worse for going that direction. So the questions are... Why would we spend power "mining" hydrogen particularly than sending it quickly in the time of the grid to the automobile's battery? Are low priced (non platinum utilising) power cells truly interior of attain?

Answer 7

The answer to your first part is NO as hydrogen is a vital component chemical part of water. Hydrogen is used to make ammonia as a fertiliser, methanol,petrol, rocket fuel. It is also added to fats and oils to make them lighter (hydrogenated). It was used in airships but was to flammable ( they switched to helium).It is lighter than air
In the classroom water (H2O) can be separated by electrolysis into separate containers one with hydrogen and the other with oxygen.

Answer 8

hydrogen is use for the making of fussion bumbs and it is also used in air ships and other industries.

Answer 9

Bombs, traveling baloons, and many industrial processes.
