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

Actually, water is the waste product of hydrogen fuel cell. Hydrogen can be used for "chemical" rockets and hopefully cars of he future. The only problem is it costs more to produce H2 than gass or oil so it's more expensive.

Answer 2

Hydrogen is used as a source for fuel, or power. The explosive force of hydrogen is quite powerful. It is what keeps us alive, all that hydrogen in the sun.

And yes, hydrogen can be separated from the oxygen in water. But as of today, the energy required to separate the atoms is higher than the amount of energy attained from the hydrogen power, so conventional methods of separating the two do not make sense.

In order to have deep sea divers using a device that produces oxygen on demand, high amount of power is required. In other words, you'd have to strap a battery the size of a car to the diver, or run a high voltage cable thousands of feet underwater and have the boat generate inordinate amounts of power to sustain the diver. Running electric lines through water..............bad idea.

But your idea is on the minds of today's scientists, it's just that the power requirement is still too high. It's why topics such as cold fusion are the holy grail in the scientific world.

Answer 3

Hydrogen is used contained in the production of ammonia, for many help reactions, as a gas and multiple different applications. confident, you may separate the oxygen from hydrogen in water and that's finished by utilising electrolysis. they have certainly invented something for people on submarines to apply that converts the sea water so as that they have got limitless quantities of oxygen devoid of re surfacing. i've got self assurance that the hindrance for a nuclear sumbarine is the quantity of nutrition mandatory for the sailors, no longer the air grant. i assume that hydrogen produced by utilising a submarine would in simple terms be bubbled away to waste, yet on land hydrogen is extremely smart certainly. Aeroplanes have been outfitted that use liquid hydrogen as a gas and those must be the destiny while the oil starts to expire. Hydrogen is an exceptionally environmentally friendly gas - it produces no CO2, CO or soot while burnt, in ordinary terms water and that is produced utilising wave, wind or image voltaic power etc.

Answer 4

It could be used as a fuel. It could also take the place of the nitrogen in scuba tanks so that divers could dive deeper and not get nitrogen narcosis or the bends.

Answer 5

It is used in industries to separate hydrogen atoms from carbon atoms in methane ... is the primary user of hydrogen as an energy fuel;

Answer 6

i thought the human body used the nitrogen content in air to breathe? then again i flunked science 10 twice because theory doesnt cut it.

Answer 7

I tend to use it to blow up people who post the same question three times!
