Question

1. cos 0 - 4 sin 0 = 1 = sin 0 + 4 cos 0 =
1)+1
2) 0
(EAN
3)+2
+4
answer it quick i already saw the answer but i have doubt can any one do it in other process​

Answer 1

Effective Atomic Number (EAN) is given as the contribution of each ligand to the central metal atom.

EAN = Atomic number of central metal atom - charge on central metal atom + 2(number of ligands).

Atomic number of Cobalt = 27

Charge on Cobalt = +3

Number of ligands = 6

Contribution of ligands = 12 electrons

EAN = 27 - 3 + 12 = 36
