Here you go! https://en.wikipedia.org/wiki/Biological_functions_of_nitric_oxide Last sentence of third paragraph: "Nitric oxide should not be confused with nitrous oxide (N2O), an anesthetic, or with nitrogen dioxide (NO2), a brown toxic gas and a major air pollutant, the latter being a product...

Hello again :tongue: Does this equation occur slowly or rapidly? 2NO(g) + O2(g) → 2NO2(g) Conquering Chemistry: "Nitric oxide slowly reacts with oxygen to form nitrogen dioxide" Wikipedia: "nitric oxide is rapidly oxidized in air" Britannica: "reacts rapidly with oxygen to form nitrogen...

Ahh I see what you're getting at, thanks. I was under the impression that concentration meant the amount of substance dissolved in water, and hence water's concentration was always constant.

Isn't there a general rule that adding a pure solid/liquid to a system doesn't affect the equilibrium? It's talked about here: http://digipac.ca/chemical/mtom/contents/chapter3/chap3_7_3.htm And a little bit here: https://web.mst.edu/~gbert/LeChatelier/LeChatelier.html

Hi guys, my first post here :smile: In the Jacaranda textbook (Pg 141-142) the reversible reaction Cu(H2O)42+ + 4Cl- ⇌ CuCl42– + 4H2O(l) is given. The textbook writes: "When water is added to the green mixture, the disturbance causes the equilibrium to shift to counteract the change. The...
