<p>Some organic reactions involve amine, but yeah, no elemental nitrogen ;)</p>
<p>As an AP Chemistry student, the answer is O2.</p>
<p>Yeah, I agree with the general consensus. I put O2.</p>
<p>@Gravitron- I was referring to elemental Nitrogen, I didn’t not say nitrogen containing compounds, in which case there would be many more reactions.</p>
<p>I know. :D</p>
<p>Btw, I like your name, it sounds cool.</p>
<p>Why thank you, kind sir (or madam).</p>
<p>Haha, I just realized I have been calling you Gravitron…didnt realize it was Graviton. Also, Im a sir.</p>
<p>I put O2 as well.</p>
<p>For somebody who forgot everything in AP Chem, I BSed it and put O2. I actually tried to use SOME AP Biology in it by thinking, “Oxygen did not exist in the atmosphere for awhile, therefore blah blah blah…–oh well I’ll pick O2.” Was not relevant to the topic at all, but hey it worked, ehh?</p>
<p>^lol by the time of fossil fuels oxygen levels were 35% as compared to 21% today</p>
<p>So? 10 char</p>
<p>Can someone explain why the answer was O2. All I remember from the passage was that it was “air” that they said did whatever it did (haha I really dont remember it at all) and I ended up choosing N2 (studying for chem sat2 I remembered that nitrogen was the major component of air lol)… so any explaining to why its O2 would be great</p>
<p>As stated before, although nitrogen gas is the major constituent in dry air, it is quite inert and doesnt react with organic compounds (diatomic nitrogen); however, oxygen does react readily with organic compounds, so the answer is O2. This is familiar from AP Chem…</p>
