This looks very much like the first part of a chemical equation: the description of the process of a chemical reaction. The conventional rules for chemical equations are that - just like mathematical/algebraic equations - the two sides must match. KBr is Potassium Bromide; I2 is iodine, which in its natural state consists of two atoms joined together, and so is written with the subscript '2'. As one molecule of iodine has two atoms, two molecules of potassium bromide must be placed in the equation to make the sides match.
If these two substances are made to react (to my recollection, since bromine is more reactive than iodine this reaction would not occur unless catalyzed in some way, say by heat) then the iodine and bromide would change places, leaving potassium iodide and bromine (a brown, very pongy gas at room temperature); so the whole equation would be:
2 KBr + I2 -> 2 KI + Br2

Is the reaction 2KBr - 2K plus Br2 endothermic or exothermic?
it is unanswered
What chemical is oxidized in the following reaction Br2(l) plus 2I-(aq) and rarr 2Br-(aq) plus I2(s)?
Bromine is the oxidizing element.
Balance this molecular equation I₂ plus HNO₃ equals HIO₃ plus NO₂ plus H₂O Example HBr plus O₂ equals Br₂ plus H₂O Balances to 4HBr plus O₂ equals 2Br₂ plus 2H₂O?
I2 + 10 hno3 = 2 hio3 + 10 no2 + 4 h2o
How much energy is needed to melt 254 grams of l2?
This is a trick question because "I2" is the chemical symbol for MOLECULAR iodine (your question did not say melt Iodine, it said melt I2).Only gaseous iodine is composed of I2 molecules and as it is a gas it CAN NOT melt.
Which direction of the reaction is favored at 298 K (room temperature)?
Toward I2(s) production
