What is the gas produced when iron(II) sulfide is treated with a nonoxidizing acid?
Art [367]

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)

Convert 5.0x10^24 molecules to liters.
Over [174]
To convert the given value we need conversion factors to relate molecules to liters. At STP, we know that 1 mol is equal to 22.4 L  and by using Avogadro's number we can relate molecules to 1 mol. Calculation is as follows:

5.0x10^24 molecules ( 1 mol / <span>6.022 x 10^23 molecules<span> ) ( 22.4 L / 1 mol) = 186.0 L </span></span>
