Checking Theories Answered

In this topic, place your theories of some chemistry experiments in the comments section, starting with this one.

To start with, Fe + 2H2O --> FeO2 + 2H...

Place iron fillings to fill 1/3 of a water bottle. Fill the rest with water, and place a balloon on top. Wait X days/weeks/months. The water reacts with the iron to extract the oxygen from the water, leaving only hydrogen, and rust in the products. In the reactants, the hydrogen was bonded to the oxygen.

Will someone tell me if this works? The energy that bonds this is the potential energy in the water.


Thank you Kiteman! I finally go a comment from you!

You're welcome!

I decided you needed a whole new comment!

Your idea of nuclear fission with H

Yes, that was my idea of fission or fusion of H, beacause the sun can do it! Then, to keep green, the earth seems to be running out of helium, which I beleive is a bi-product of H fusion or fission.

Hydrogen can't "fission", since its nucleus consists of a single proton. Hydrogen fusion requires extreme temperatures (millions of degrees) and pressures (thousands of atmopheres) because the natural repulsion of the two positive charges is so high. I leave it to you to actually do some research (ask your science teacher if you don't know how to use the library) to verify these statements quantitatively.

Helium in the Earth's crust is not a byproduct (check your spelling) of fusion. It forms as a result of radioactive decay of naturally occurring uranium and thorium (primarily), both of which produce alpha particles. Alphas are nothing more than helium nuclei, so once they come to rest in whatever rock the U or Th was part of, they eventually pick up a couple of electrons and become helium atoms.

The Earth is "running out" of helium in the outer crust because we extract it faster than it's produced (like so many other things humans do).

Thank you, somebody finally gave a lengthy and very helpful article upon why this wouldnt work. Now, I get that this wouldnt work. Anybody else have some ideas?

Well, what is it you're actually trying to do? Do you want to generate hydrogen from some chemical reaction? You can find plenty of methods in any freshman physical chemistry text. Are you trying to violate energy conservation? You can find plenty of crackpots who claim to have methods, but none of them will stand up to scrutiny.

No, just a passing thought... anyways, do you have any other ideas?

Is that "Am" (i.e., everybody's favorite smoke detector source?) or "antimatter"? If the latter, what are you keeping it in?


No, it's "Adrian monk" everybody's favorite ibler!

Yes, you were lucky to get away with most of you in tact! *shakes fist* I'll get you next time!!!!

Sorry, that's wrong. The iron reacts with oxygen dissolved in the water. You can confirm this by using freshly-boiled water, which has little or no dissolved oxygen (the first bubbles formed when you heat water are gases coming out of solution) - the iron will not rust to anything like the extent.

If the OP experiment were to actually work (it never will but still) wouldn't iron need to be more reactive than hydrogen to cause such a displacement reaction?

It's more than a displacement reaction (I think), because the two hydrogens are on either side of the oxygen. The iron atom would have to "get at" both at once...?

Also, O2 is not Dissolved in water, as Dihydrogen Monoxide is H20.

Did you read any of the links NM referenced? O2 is most certainly dissolved in water, as is N2 CO2 and any other ambient gas.

How do you think fish breathe? Water molecules are amazingly stable -- cells absolutely don't dissociate the oxygen from the hydrogen (not directly). Fish respiratory systems set up an osmotic system, where the oxygen dissolved in the ambient water comes out of solution through a semipermeable membrane (gas exchange).

Well, question awnsered, any experiments you would like to try?

. Verify! On the no H2 liberation, I'm depending on memory of classes I took over 30 years ago.

Hmmm... I see. Then, if Fe is left outside, it will rust. Humidity will not affect this?

. Yes, Fe left outside (or inside) will rust. Fe is not that reactive, so it happens slowly. Any moisture, humidity included, will accelerate the process. Cars abandoned in the desert will last much longer than ones abandoned in a forest.

. IIRC, the Fe is reacting with O2 dissolved in the water (DO), so, no. It's been a while since I took Chem class, so I may not remember correctly.
