Explain....

plz.................... ​

Answer 1

Answer:

Hey mate

Here is your answer

IUPAC name of K₂[Cr(CN)₂(O)₂(O₂)(NH₃)] is potassium amminedicyanodioxoperoxocromate(VI)

Well, Let's check it is true or false.

oxidation state of oxo, (O) = -2

oxidation state of peroxo (O₂) = -2

oxidation state of ammimo (NH₃) = 0

oxidation state of dicyano (CN) = -1

Now, [(Cr(CN)₂(O)₂(O₂)(NH₃)]⁻⁻ + K²⁺

Let oxidation state of Cr = x

x +2(-1) + 2(-2) + (-2) = -2

x = +6

Hope it helps.
