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

    Jan 14, 2015 · $\ce {H_ {2}O}$ is the water molecule, two hydrogen atoms attached to a central oxygen atom, $\mathrm {C}_ {2v}$ symmetry, thermodynamically minimal structure of these atoms, Adam's …

  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. 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. …

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

    Oct 27, 2022 · I'm sorry, but having a megajoule of an explosive gas mixture nearby is NOT something you want to do (particularly since it can be set off by a static discharge). For example, stored …

  5. 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 …

  6. 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 …

  7. 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 …

  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. Oxidation of SnCl2 to SnO2 using a hydrothermal route

    Jan 24, 2026 · Beside hydrothermal synthesis route you are following, there is an another way of getting X2 2 nano-single crystals using high temperatures (Ref.1): [...] At a heating rate of 5 ∘Cmin−1 5 ∘ C …

  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 …
