Question
Use and preparation of hydrogen sulfide Hydrogen sulfide, H2S, is often used as a qualitative tool to detect and separate metal ions by formation of sulfide precipitates. H2S can be generated from metal sulfides by reaction with dilute acids. Part A How many liters of H2S gas could be generated at STP from the reaction of dilute HCl with 15.55 kg of an ore that is 25.7% iron(II) sulfide by mass?Pleas show steps :) Use and preparation of hydrogen sulfide Hydrogen sulfide, H2S, is often used as a qualitative tool to detect and separate metal ions by formation of sulfide precipitates.

Explanation / Answer
FeS + 2 HCl ---> FeCl2 + H2S
ore weight=15.55 kg
Fes weight=15.55*(25.7/100)=3.996 kg=3996 g
Fes molecular weight=87.91
from reaction
87.91 g of FeS produce 22.414 lit(1 mole) of H2S
3996 g of FeS produce =(22.414/87.91)*3996=1018.841 lit
liters of H2S gas could be generated = 1018.841 lit
