Chlorine is a more reactive halogen than bromine, therefore, when chlorine gas is bubbled through a calcium bromide solution, the chlorine will take the place of the bromine. This is called an anionic single replacement (displacement) reaction.
Cl2(g) + CaBr2(aq) --> Br2(l) + CaCl2(aq)
Chlorine is a stronger oxidizer than elemental Bromine. So, when yellowish chlorine gas is bubbled through the Bromide solution, a red colour is formed which is Bromine. Chlorine oxidizes Bromide ions to elemental Bromine while itself is reduced to Chloride ions. So, the total reaction is: Cl2 + Br- ----> Br2 + Cl-
Single-replacement
you get HCl and HClO
Chlorine gas is bubbled through the water, where it combines with the water to form hypochlorous acid (HOCl) and hydrochloric acid (HCl).
H2S + FeCl2 --> FeS + 2 HCl The iron sulfide will precipitate out, making this reaction nonreversible.

2(FeBr3) + 3(Cl2) --> 2(FeCl3) + 3(Br2)
The chemical reaction is: 2NaBr + F2 = 2NaF + Br2

you get HCl and HClO
Displacement scratch that it a single replacement

Chlorine is bubbled through molten dore, converting the metals into chlorides.
from colourless(solution) to brown(solution)
it because of the ammonium ion form in the solution. Ammonium solution is an alkaline.
The carbon dioxide will change into a milky solution . If we further bubble through lime water the solution we be colourless.
