  1. Differences between H-H-O and H-O-H - Chemistry Stack Exchange

    Jan 14, 2015 · To add to this, there are exceptions to the 'hydrogen only makes one bond' rule of thumb, in the form of unusual electron-deficient bonds as found for instance in boranes, however this does …

  2. Reaction of potassium with water - Chemistry Stack Exchange

    Jun 5, 2019 · The reactions are ongoing this way: Relatively free electrons of potassium reduce water: $$\ce {2 e- + 2 H2O -> H2 + 2 OH-}\tag {1}$$ That leaves metal positively charged. Liquid ammonia, …

  3. Is oxyhydrogen lighter than air? - Chemistry Stack Exchange

    Oct 27, 2022 · This is a matter of simple calculation. If you don't know how to calculate it, then all this looks like just another reason not to anything like that.

  4. electrochemistry - What metals are safe to use as electrodes when …

    May 5, 2022 · I am going to be a DC power converter (with fairly high voltage and amps) to turn water into hydrogen (and oxygen) gases. However I have a few questions about the safety of this process. …

  5. How does high-frequency electrolysis of water work?

    Feb 20, 2022 · I have read that combining the DC current with a high-frequency AC current, the electrolysis of water speeds up. Is this true? In that case, how is less energy wasted as heat? Or …

  6. Can hydrogen and oxygen gasses be turned back into water?

    Oct 3, 2016 · I electrolized water today, and got hydrogen. And I have a bottle of oxygen. Can I combine those to get myself water? I know $\\ce{H2O}$ is super pure water, but I just want to try. Is this too …

  7. Why is it OH- and not HO-? - Chemistry Stack Exchange

    I am told that in a chemical equation the metal comes first and then the non metal. for example MgO, ZnSO 4,etc. But when both the elements are non metals or metals, the one with the lower atomic …

  8. phase - At what pressure will hydrogen start to liquefy at room ...

    Sep 21, 2020 · I want to increase a fixed-size object's internal gas pressure by generating hydrogen in it, but I could not find the proper phase diagram for it. So I am wondering how high pressures I can get.

  9. inorganic chemistry - Why does hydrogen fluoride have a boiling point ...

    Aug 22, 2015 · @orthocresol It is known that HF shows hydrogen bonding in gaseous phase too. It simply means that while going from liquid to gaseous phase, the hydrogen bonds don't have to be …

  10. Can natural gas appliances run on Hydrogen? - Chemistry Stack …

    Jun 22, 2013 · Pure hydrogen, as opposed to hydrocarbons, degrades metals. $\ce {H_2}$ molecules are tiny, so they wedge themselves into the relatively large metallic crystal structures and form …
