In absence of air, Hydrogen reaction

[Butterfly_grl]

What is the reaction of hydrogen and oxygen say in a vacant tube in absence of air, does it give Water, or hydrogen peroxide? and the amount of hydrogen and oxygen is the same of water ratio 2:1

In the Kanzius experiment, the hydrogen and oxygen are produced (together) and not ionized, so the hydrogen and oxygen are causing fire because of their reaction with air? and if they are the same ratio of water, why don't they give water back?

and in the same experiment, if the hydrogen and oxygen are also produced, in a vacant tube, would they produce a spark?

Thank you.​

H2 and O2 when burnt forms water.

Peroxide needs a catalyst to form from O2 and H2, the catalyst is an Au-Pd mix suspended in Al2O3. Peroxide can also be formed using this method http://en.wikipedia.org/wiki/Hydrogen_peroxide.

H2O2 will breakdown exothermically to make water and oxygen.Need to read up on Kanzius' experiment.

I can provide some insight into the reactions of hydrogen and oxygen in the absence of air. Without the presence of air, the reaction between hydrogen and oxygen will not produce water or hydrogen peroxide. This is because water and hydrogen peroxide require the presence of air (specifically, oxygen) to form.

In the Kanzius experiment, the hydrogen and oxygen are produced together and not ionized. This means that they are not in their separated forms and are not able to react with each other. In order for a reaction to occur, the hydrogen and oxygen must be in their individual forms and in the presence of air. This is why they do not produce water or hydrogen peroxide in the Kanzius experiment.

Additionally, the ratio of hydrogen and oxygen in the experiment may not be the same as the ratio in water. This is because the production of hydrogen and oxygen in the experiment is likely not a controlled process, so the ratio may vary. In order for water to be produced, the ratio of hydrogen to oxygen must be 2:1.

In regards to the production of a spark in a vacant tube, it is unlikely that a spark would be produced without the presence of air. A spark requires oxygen to sustain the reaction and without air, the reaction between hydrogen and oxygen will not occur.

Overall, it is important to understand the specific conditions and components necessary for a reaction to occur. In the absence of air, the reaction between hydrogen and oxygen will not produce water or hydrogen peroxide, and a spark will not be produced without the presence of air.
