== "High-energy oxygen" theory ==

The claim, currently included in the lede, that


== Oxygen-15 natural occurrence ==
:[[Allotropes of oxygen#Dioxygen|Dioxygen]] provides most of the [[chemical energy]] released in [[combustion]] and aerobic [[cellular respiration]]


Shouldn't oxygen-15 be listed as "trace" rather than "synthetic" , since trace ammounts are produced naturally by lightning and in the sun. [[Special:Contributions/174.103.211.189|174.103.211.189]] ([[User talk:174.103.211.189|talk]]) 04:20, 7 December 2023 (UTC)
is part of a very wide campaign by a Wikipedia editor to insert references to his theory in many science articles (so if you're trying to research it on Wikipedia, you'll likely come across another page edited in the same way by the same person). This theory, which describes oxygen as a "high-energy" molecule, is pretty fringe-y, and culminates in such statements as


== oxygen is not the most abundant element on earth. iron is ==
:the lower heating value is directly proportional to the amount of oxygen consumed in the combustion


thought that should be changed [[Special:Contributions/2605:A601:AA0D:F900:9CA4:FB25:36E:D726|2605:A601:AA0D:F900:9CA4:FB25:36E:D726]] ([[User talk:2605:A601:AA0D:F900:9CA4:FB25:36E:D726|talk]]) 05:51, 6 January 2024 (UTC)
which, of course, it isn't. Branched alkanes differ in their heating value (but not in the amount of oxygen consumed in their combustion) from the unbranched alkane they are based on. (See also [[ring strain]], [[aromaticity]], [[triple bond]]).


:Oxygen is the most abundant specifically on Earth’s crust [[Special:Contributions/99.17.2.140|99.17.2.140]] ([[User talk:99.17.2.140|talk]]) 08:50, 16 January 2024 (UTC)
(It's well-known that for restricted classes of fuels, a rough approximation of the heating value can be obtained by considering only the elemental composition of the fuel, or even just the amount of oxygen required for its combustion. See [[Weir formula]] for a 1949 paper that's pretty clear about that.)


::Define abundance. By number fraction, i.e., actual number of atoms, oxygen is by far more abundant over the entire Earth. There is a greater mass fraction of iron but that's simply because it's heavier. However, as stated in the article, there is a greater abundance of oxygen by mass in the Earth's crust and biosphere. <small>'''''[[User:Polyamorph|Polyamorph]]''''' ([[User talk:Polyamorph#top|talk]])</small> 13:15, 16 January 2024 (UTC)
I strongly feel this theory should be removed from Wikipedia. It's non-notable, violates the scientific consensus, has been introduced by a single COI editor, and I believe (though others may feel differently) that it qualifies as both a fringe theory and pseudoscience. Asking whether it's the oxygen or the fuel which "provides" the chemical energy for a reaction is a question which, in standard chemistry, simply makes no sense. (It does make sense, of course, if you consider nuclear energies, but the results are then very different from the predictions of this theory).


== Lavoisier's contribution, "Sur la combustion en général", mentions neither "vital air" or "azote" ==
I've brought this up in a number of places:
* the author's talk page at [[User talk:Klaus Schmidt-Rohr#Photosynthesis]]
* WP:FTN at [[Wikipedia:Fringe theories/Noticeboard#Chemical energy and related articles]]
* my user page is where I currently keep notes: [[User:IpseCustos]]
* individual articles' talk pages. Unfortunately, there's quite a few.


I've been doing some basic research into the etymology behind Oxygen, and found that Lavoisier's contribution states that:
I've also fixed a few pages, but was, of course, reverted.


::''This and other experiments on combustion were documented in his book Sur la combustion en général, which was published in 1777. In that work, he proved that air is a mixture of two gases; 'vital air', which is essential to combustion and respiration, and azote (Gk. ἄζωτον "lifeless"), which did not support either.''
My question is two-fold:
# If I'm wrong and it's actually perfectly good science and in accordance with Wikipedia's principles, could someone please tell me?
# If I'm right and Wikipedia has been widely damaged in an attempt to push pseudoscience, how do I fix it? Is an RfC the next step?


However when actually reading "Sur la combustion en général", neither "vital air" nor "azote" are ever mentioned:

== "High-energy oxygen": I'm sorry this discussion is a mess ==


The closest he came to defining either (as far as I could find) is the line:
The discussion concerning "high-energy oxygen" is a mess. That's my fault, and I'm sorry and will try to do better in future, choosing a single central venue for discussion when possible.


::''Ainsi, pour résumer, l’air est composé, suivant moi, de la matière du feu comme dissolvant, combinée avec une substance qui lui sert de base et en quelque façon qui la neutralise''
* Most of it is on [[WP:FTN]] at [[WP:FTN#Chemical energy and related articles]].
* Some of it is on [[User talk:Klaus Schmidt-Rohr]] and [[User talk:IpseCustos]].
* Some of it is on [[Talk:Photosynthesis]].
* Some of it is on this page, [[Talk:Oxygen]].
* There's a plea for help on [[Wikipedia Talk:WikiProject Chemistry]].


In English:
Since so many articles are involved (57 articles assigning the chemical energy of oxidation to the oxygen molecule), I might have missed some.


::''Thus, to summarize, air is composed, according to me, of the matter of fire as a solvent, combined with a substance which serves as its base and in some way which neutralizes it.''
Again, I'm sorry, I realize this is making life harder for other editors who just want to get an overview. If there's anything I can do to actually improve the situation, rather than adding more and more posts to various discussion forums, please let me know?


The wikipedia text that claims he called these "vital air" and "azote" stems from reference [18]: "The Encyclopedia of the Chemical Elements." [https://archive.org/details/encyclopediaofch00hamp/page/500/mode/2up]https://archive.org/details/encyclopediaofch00hamp/page/500/mode/2up

:I am a published expert in chemical energy and bioenergetics, the field under dispute here, and have credentials as a Fellow of the American Physical Society and of the American Association for the Advancement of Science. Everything I have written on this topic builds quantitatively on chemical textbook principles of the relations between bond strengths, chemical energy, and heat or free energy release. According to these textbook principles, conversion of relatively weak electron-pair bonds, as found for instance in O<sub>2</sub>, to stronger bonds releases energy, which means that relatively weak bonds store chemical energy. I have not deleted other editors’ content in any major or disruptive manner but rather ''added'' fairly brief technical statements prompted by the context (and have also made numerous unrelated advanced technical edits in articles within my expertise, e.g. on formal and applied thermodynamics, chemical equilibrium, kinetics, acids/bases, mass in special relativity, NMR spectroscopy, electrochemistry, statistical mechanics, materials, solubility, etc.).

:Examples of questions answered include:
:
:- Why is combustion or aerobic respiration of organic molecules always exothermic, and why is the heat of combustion of an organic fuel in a fire (LHV) directly proportional to the amount of O<sub>2</sub> consumed?
:- Why do carbohydrates have less than half the heat of combustion, per gram, of fat?
:- Why does fermentation of glucose produce only 2 ATP, while respiration of glucose + 6 O<sub>2</sub> produces 30 ATP? (Attributing this difference to incomplete decomposition of glucose in fermentation is invalid, because splitting glucose up all the way into 3 CO<sub>2</sub> + 3 CH<sub>4</sub> releases only 15% of the energy of glucose combustion with 6 O<sub>2</sub>, and complete decomposition of glucose into 6 formaldehyde molecules would release no energy at all.)

:My brief explanations answering these questions in relevant Wikipedia articles have led to friction with editors who for some reason seem uninterested in providing explanations of such notable facts (even after repeated prompting, they have not shared sources showing alternative valid explanations of the notable science questions listed) and accepting their conceptual consequences.
:
:In any case, as soon as I understood the viewpoints and expectations of other editors, I started to work on consensus phrasing that took these concerns into account where possible. Specifically, we have consensus that in general terms combustion and aerobic respiration “releases the chemical energy of fuels/nutrient molecules and oxygen”, and I have accordingly revised the contested phrasing in a significant fraction of the articles in question. '''Can we build on that consensus?''' In a few other cases, I have documented every important statement with a reliable secondary source (textbook with specific page number or official standard) and thus fully met Wikipedia requirements.

:In the course of this discussion, individual editors have opined that incorrect statements are fine on Wikipedia or that experts should not edit in their area of expertise; notable scientific facts backed by reliable secondary sources (textbooks) have been deleted. This is rather disappointing.

Lavoisier's contribution, "Sur la combustion en général", mentions neither "vital air" or "azote"

[edit]

I've been doing some basic research into the etymology behind Oxygen, and found that Lavoisier's contribution states that:

This and other experiments on combustion were documented in his book Sur la combustion en général, which was published in 1777. In that work, he proved that air is a mixture of two gases; 'vital air', which is essential to combustion and respiration, and azote (Gk. ἄζωτον "lifeless"), which did not support either.

However when actually reading "Sur la combustion en général", neither "vital air" nor "azote" are ever mentioned:

[1]https://www.academie-sciences.fr/pdf/dossiers/Franklin/Franklin_pdf/Mem1777_p592.pdf

The closest he came to defining either (as far as I could find) is the line:

Ainsi, pour résumer, l’air est composé, suivant moi, de la matière du feu comme dissolvant, combinée avec une substance qui lui sert de base et en quelque façon qui la neutralise

In English:

Thus, to summarize, air is composed, according to me, of the matter of fire as a solvent, combined with a substance which serves as its base and in some way which neutralizes it.

The wikipedia text that claims he called these "vital air" and "azote" stems from reference [18]: "The Encyclopedia of the Chemical Elements." [2]https://archive.org/details/encyclopediaofch00hamp/page/500/mode/2up

In 1777 he published his work on combustion under the title "Sur la combustion en general." Lavoisier showed that air is essentially a mixture of two gases, which he called "vital air" and "azote."

I don't disbelieve that Lavoisier started calling the two components of air "vital air" and "azote" at some point after his discovery, and the etymology of Oxygen aligns well with him mentioning that a lot of combustions produce acid later in the paper.
