Iodine, I2 and bromine, Br2, react in a closed 2.0-L container at 150ºC to produce iodine monobromide, IBr, according to the following equation: I2 + Br2 2 IBr
The equilibrium constant, K, at this temperature is 1.2 x 102. What are the equilibrium concentrations of all entities in the mixture if the container initially contained 4.00 mol each of iodine and bromine?

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
