In electrolysis of H2O, H2 & O2 are left. If you kept splitting H20 and burning it would the world run out?

Question

Of water?

Answer 1

Yep, and please don't.

Answer 2

No, because the oceans are a practically infinite supply of fuel. In addition neither hydrogen nor oxygen are lost during combustion; they simply combine with other molecules to make other chemicals.

Answer 3

No, you would never run out of water.  The molecules are not destroyed.  The process is very inefficient and would require large energy input to keep it going.  The planet is actually gaining water from asteroids and meteors.

Answer 4

No

Answer 5

you get two (2) atoms of hydrogen and one (1) atom of oxygen when you separate them.

when you "burn" hydrogen you are simply recombining them again.

Answer 6

No. it does not work that way.

Currently unburned fuel combines with oxygen, but have you noticed that we are running out of oxygen.

The reaction is very complex. Some plants absorbs CO2 and emits O2.

The balance equations are not as simples as sounds.

Answer 7

no. if you burn hydrogen and oxygen you get water, so you're back where you started. but that's not really of any matter, because to electolyse all the worlds seas and oceans would be an impossibly massive chalenge.

Answer 8

no...its impossible to destroy the elements...they just change form. What is formed is O2 and H (not H2)...when you burn the H, it produces energy and the result of that combustion is water..you combine the O2 during combustion with the H. Now, it takes more energy to break those bonds so its not a perpetual motion machine...you cannot violate the laws of thermodynamics.
