Essentially all the available nitrogen for life in the form of nitrates and ammonia would eventually disappear. Nitrogen is needed to make proteins and other chemicals so it is required for all life to exist. It gets recycled so it would take many decades in most places before the available nitrogen ran out. Many crops like beans depend on it. Humans can manufacture it but it would be hard on the ecosystems of the world and eventually probably lead to the extinction of all the ecosystems of the world.
Hope this helps!
Answer:
Hydrogen sulfide
Explanation:
A nonoxidizing acid is the acid which cannot act as oxidizing agent and thus furnish hydrogen ions. Example: HCl
Iron(II) sulfide reacts with nonoxidizing acid, say hydrochloric acid to give rotten egg smelling gas, H₂S (Hydrogen sulfide).
The reaction is shown below:
FeS (s) + 2HCl (aq) ⇒ FeCl₂ (s) + H₂S (g)
A general reaction is also shown below of the reaction of Iron(II) sulfide with any nonoxidizing acid, HX as:
FeS (s) + 2HX (aq) ⇒ FeX₂ (s) + H₂S (g)
