Question

The reaction of cl2 + 2 k i gives 2k kcl + i2 conversion of to i2 i2 is deemed as

Answer 1

Explanation:

Look at the periodic table and find out which orbital type is filled with electrons first.  

(a) The 2s orbital (containing the outermost electrons of Li and Be) is filled before the three 2p orbitals (containing the outermost electrons of boron through neon). Thus the 2s orbital is of lower energy.  

(b) The three 3p orbitals (containing the outermost electrons of Al thru Ar) are filled before the five 3d orbitals (containing the outermost electrons of Sc through Zn). Thus the 3p orbitals are of lower energy.

c) 3s < 4s  

d) 4d < 5f

Answer 2

Answer:

I think oxidation

Explanation:

On LHS

Iodine is in ionic state

(I²‐)

In RHS

Iodine is in molecular state

Thus it loses electrons
