Talk:Nitrogen oxide

message: Given the atmospheric importance of NO and NO2 which have a fast cycle coupling them and the regulatory use of NOx for the sum of NO plus NO2 (in atmospheric chemistry other oxides of nitrogen are not part of NOx) I do not think that NOx should be part of the Nitrogen oxide page. I therefore call for the reinstatement of the NOx page.--NHSavage 07:19, 7 September 2005 (UTC)
replies: text: Agree. The majority of this page is currently discussion about NOx instead of Nitrogen oxides in general. I've inserted a tag at the appropriate location.  —Preceding unsigned comment added by Grayob (talk • contribs) 13:51, 4 June 2009 (UTC)

thread_title:  NOx should have its own page 

message: There's no explanation as to what is Prompt NOx and how its formed. It might also be interesting to add the names of the people normally credited with discovering these NOx formation routes (Zeldovich in the Thermal NOx case and Fenimore in the Prompt NOx case)
:I was lured to this page as I was about to ask what "prompt NOx" is myself. I was thinking of asking the person responsible for originating the text but they were an IP number long inactive with only 1 edit. Can anyone enlighten me or provide a reference?  By the way, not a bad idea about the discoverers.   -Onceler 02:27, 9 February 2006 (UTC)

thread_title: Lightning

message: Parts of this article are highly misleading. NOx is not considered a greenhouse gas. It doesn't say so in the article either, but nor is there any mention of why NOx is regulated. The reason for the regulation is that NOx emissions causes acidification of water and soil, and also is the cause of adverse effects such as respiratory diseases and immune deficiencies among asthmatics and other vulnerable groups.   
Nitrous oxide (N2O) is a greenhouse gas, and it is included in the Kyoto Protocol, but regulations on emissions have not been widely implemented in national legislations, and it is not part of most existing cap and trade systems.
I strongly agree with earlier posting by NHSavage that NOx should have it's own article. Also, 
Not being a biochemist I would strongly prefer not being the one to make these changes, but if no one else rises to challenge, I will take a look at it in a couple of weeks, when I have the time.

thread_title:  Misleading about NOx 

message: According to Seinfeld and Pandis, 1998, Atmospheric Chemistry and Physics, "nitrogen oxides" refers to NOx (NO+NO2).  "Reactive odd nitrogen" refers to NOy, which is NOx + all the oxidation products of NOx.  N2O is considered its own class (Nitrous oxide).  In discussions with a couple of friends who have PhDs in atmospheric chemistry, we agreed that we would assume that someone talking about "nitrogen oxide" would be referring to NOx, even if one could technically make the argument that a nitrogen oxide is any nitrogen-oxygen compound. 
Additionally, the U.S. Clean Air Act specifically states: "(v) NOx.—The term ‘‘NOx’’ means oxides of nitrogen."
Not being a wikipedia regular, I hesitate to make drastic changes to the page myself, but I wanted this on the record for a more frequent wiki editor to consider adding "common scientific usage" or the like to the page. 2marcus (talk) 20:04, 2 November 2009 (UTC)

thread_title:  Other NxOy compounds? 

message: This article needs to be more than just a disambig page. A reader coming here to find out more about some nitrogen oxide or other may be surprised to find there are so many and have no idea which of them is the one they want to learn more about. A short discussion of their comparative properties, uses and any common names or other distinguishing characteristics would be very helpful in recognising the context which brought the reader here. — Cheers, Steelpillow (Talk) 15:19, 23 October 2019 (UTC)
replies: text: I suppose so. But with the common source being internal combustion engines producing a mixture of most of them, it is reasonable to have an article on them together.  Well, the common term for car exhaust is NOx, so maybe an article more specific to engine exhaust would be useful.  Otherwise, why isn't the article title plural, since it refers to all of them?

thread_title:  More than just disabmig 

message: The article currently states: "Nitrogen oxide may refer to a binary compound of oxygen and nitrogen....".
However I cannot see it explained what "binary compound" actually means.
"Binary compound" links to the binary phase [phase] page which is also confusing or maybe plain wrong. (I will explain with a note on that page's talk section too).
I did some chemistry, but not as a major, so someone else could better fix this.
I suspect the word PHASE in chemistry refers to phases such as solid, liquid, and gas.
Nitrogen oxide exists in different ways e.g. NO2, NO, N2O etc. and I wonder if that is what the original sentence was suggesting? A similar concept to polymorphism, but i can't find the correct term at the moment!

replies: text: I added 'binary compounds' to binary compound (which redirects to binary phase). It just means the molecule is made up of 2 types of atoms - in this case nitrogen and oxygen.  Stepho  talk  12:07, 17 December 2019 (UTC)
