Although all the hydrogen in the sun and the stars will eventually be converted to helium or heavier elements, there is likely to be plenty of hydrogen atoms in outer space. This answer assumes, in line with current cosmological theories, that the universe does not end in a big crunch.
not possible
Wet hydrogen is collected over a water surface.
Hydrogen is highly soluble in air. You won't be able to collect it it over air. Hence other methods are preferred
Switch2hydrogen.com is a fantastic website that sells hydrogen generator equipment. The website also talks about the importance of using hydrogen over gas.
The hydrogen left over.
When Hydrogen Is Passed Over Hot Tubgsten Oxide (WO3) WO3 + 3H2 ----------------> 3H2O + W
It is called wet hydrogen gas because it is collected over water.
The amount of hydrogen in a star decreases over time because the star fuses hydrogen into helium in its core through the process of nuclear fusion. This conversion of hydrogen into helium releases energy that powers the star and results in a gradual depletion of its hydrogen fuel source.
You can use a lit splint and hold it over where you think the hydrogen is, and if you hear a loud squeaky pop sound it will prove the existence of hydrogen there. You can also test of hydrogen using a Hydrogen Leak Detector.
If you are testing for hydrogen, the simplest way is to trap it in a container and release it over a fire; like a Bunsen burner. If it ignites with a satisfying, squeaky pop, then you have found Hydrogen.
Hydrogen fuel cells are very similar to batteries. They use a chemical reaction between atoms to produce their energy. •It has two electrodes, an anode and a cathode, separated by a membrane. Oxygen passes over one electrode and hydrogen over the other.
get over it this will never be answeres so get over it idiot
