Br2 + CaI2 ----> CaBr2 + I2
bromine and iodine are diatomic molecules
In a single replacement reaction between bromine and barium iodide, bromine will replace iodine in barium iodide, forming barium bromide and iodine gas. The balanced chemical equation for this reaction is 2Br₂ + BaI₂ → 2BaBr + I₂.
Br2 (g) + 2 KI (aq) 2KBr (aq) + I2 (s)
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)
Its actually: 2KI(aq)+Br2(aq)-> I2(s)+2KBr(aq)
The formula for the ionic compound formed by calcium and bromine is CaBr2. Calcium, a group 2 element, has a 2+ charge while bromine, a group 17 element, has a 1- charge. To balance the charges, two bromine ions combine with one calcium ion to form CaBr2.

The chemical reaction is:2 HI + Br2 = 2 HBr + I2
Br2 (g) + 2 KI (aq) 2KBr (aq) + I2 (s)
The oxidation state of bromine in calcium hypobromite (Ca(BrO)2) is +1. This is because the calcium ion has a +2 charge, and since hypobromite (BrO-) ion has an overall -1 charge, the bromine atom must have a +1 oxidation state to balance the charges.

Bromine is a liquid at room temperature, but after 58,8 0C bromine become a gas.
No, bromine gas is not a compound. It is a diatomic molecule consisting of two bromine atoms bonded together.
The balanced equation for the reaction between hydrogen gas (H2) and iodine gas (I2) to form hydrogen iodide gas (HI) is: H2 + I2 → 2HI
Bromine gas has a reddish-brown color.
What happens to bromine gas in a sealed tube when it is cooled and later heatedAnswer:When bromine is cooled and then heated in a sealed container, the bromine juice starts evolving in a gaseous state. It then becomes a gas i.e. bromine gas which is red-brown in color
