Why does Hydrogen create water, and not hydrogen peroxide when it burns?

Answer 1

Because you are oxidiziding hydrogen

2H2 + O2 --> 2H2O

The structure is H-O-H

Hydrogen peroxide is something else entirely

look at the structure:

H-O-O-H

It's a "Per"oxide which is an unstable molecule a combustion tempertures, and has to be made in a different way.

This is how it's done:

Hydrogen peroxide is manufactured today almost exclusively by the autoxidation of 2-ethyl-9,10-
dihydroxyanthracene to 2-ethylanthraquinone and hydrogen peroxide using oxygen from the air. The anthraquinone derivative is then extracted out and reduced back to the dihydroxy compound using hydrogen gas in the presence of a metal catalyst.

H2 + O2 --> H2O2

Answer 2

Water is made of 2 hydrogen and 1 oxygen...so there is your answer. Hydrogen peroxide is another chemical component, so when you try to change it to gas by burning it would likely not turn into water.

Answer 3

hiya those with HEARTBURN issues!! i got here across this talk board by using fact i desperate to purpose eating a a million/2 tspoon of the common OTC Hydrogen Peroxide (Brown Bottle Stuff). there's a particular portion of my decrease esophagus that usually burns way greater effective than the different section when I get heartburn, and reflux. I kinda laid at a place that should enure the Peroxide might hit that undesirable spot. I might desire to assert, it labored greater ideal than something i've got ever used. instant alleviation, and no weird and wonderful sugar crash, or despite feeling i'm getting while i take advantage of Tums, or Mylanta. i've got basically tried this thrice interior the previous 24 hours. So do no longer bypass nuts people. yet i might advise attempting it. do no longer bypass swigging from the bottle. Lemme know the way it truly works out for you.

Answer 4

Because in the reaction of Hydrogen with Oxygen, the water formed is MORE STABLE. Water is a more stable product than H2O2-peroxide. Of course, the peroxide is formed under different conditions, but the direct reaction of hydrogen with oxygen goes to a one step completion to water.

In thermodynamics, the reactions proceeds preferentially to produce a more stable product. A more stable product has "less energy" and is more thermodynamically formed. In this case, water.

Remember, chemical reactions produce products that are favored thermodynamically. Note your delta G(free energy), deltaH (enthalphy) , delta S(entropy)

Answer 5

Because peroxides are inherently unstable - if the products were to enter a peroxide phase (which they don't), the peroxide would continue to oxidize the hydrogen and you would end up with H2O anyway.

Answer 6

H2O2 (H-O-O-H) can be looked upon as an intermediate to the formation of water from H-H and O=O. Once the reaction starts, its is very energetic and hard to stop at the HOOH point.

Answer 7

When a material burns, its all elements will be oxided to the highest oxidation state & the oxidizing agent (O2) will be reduced to its lowest that's -2 & is in water, not H2O2 (-1).

Answer 8

that is just the natural chemical reaction, h2 + 02 -> h20 unbalanced equation.
