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.

The balanced full molecular equation for this reaction is: 2FeBr3(aq) + 3Cl2(g) -> 2FeCl3(aq) + 3Br2(l)
The chemical reaction is: 2NaBr + F2 = 2NaF + Br2

The reaction is a redox reaction where chlorine gas oxidizes iodide ions to form iodine molecules, while the chlorine is reduced to chloride ions. This is a single displacement reaction where chlorine displaces iodine in sodium iodide to form sodium chloride.

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.
When carbon dioxide is bubbled through lime water, the lime water turns milky due to the formation of calcium carbonate, a white precipitate. This is a common test for the presence of carbon dioxide gas.
