What is the balanced chemical equation for this reaction: …

15/5/2018· "Cl"_2("g") + "2KBr(aq)"rarr"Br"_2(l) + "2KCl(aq)" This is a single replacement reaction in which a more reactive halogen (group 17/VIIA) replaces a less reactive halogen in a compound. The reactivity of the halogens relative to one another decreases down the group. Since chlorine is above bromine, it is more reactive and will replace the bromine in the potassium bromide compound. …
