the product is Fe2S3+6HCl. i just finished the same worksheet :)
H2S + FeCl2 --> FeS + 2 HCl The iron sulfide will precipitate out, making this reaction nonreversible.
Single-replacement
you get HCl and HClO
from colourless(solution) to brown(solution)
it because of the ammonium ion form in the solution. Ammonium solution is an alkaline.

Hydrogen.
If ammonia is bubbled through an acid, an ammonium salt and hence ion of that acid is formed. Ammonia bubbled through HCl would form ammonium chloride.

Because they are two physically different, albeit closely-related chemical compositions:Hydrochloric acid is what is generally used as a strong acid in industry and retail for use in swimming pools. It is an aqueous solution of HCl, which is a strong acid and therefore dissolves fully in the solvent (water) existing as it's constituent ions H+ and Cl-, separated and interacting with the very polar water molecules. Hydrochloric acid cannot be simply dried/evaporated to create Hydrogen Chloride.Hydrogen Chloride is the anhydrous form of the molecule HCl as a ionic molecule. It is sometimes referred to as dry HCl or HCl(g), since there is no solvent present and at STP it exists as a gas. This Hydrogen Chloride can be simply bubbled through water to produce Hydrochloric acid. The reverse transformation is not possible, instead a chemical reaction must be used to create Hydrogen Chloride from various reagents (such as Sulfuric acid and Sodium Chloride)
The carbon dioxide will change into a milky solution . If we further bubble through lime water the solution we be colourless.
The hydrogen carbonate indicator is a dark, deep red, but then turns a brighter and richer colour red. :)
