hope it helps you

Answer 2

IUPAC name of $K_2[Ni(Cl)_4]$ is potassium tetracyano nickeltate (II)

Explanation:

Rules for naming of the coordination compounds :

1. The ligand named first then metal.

2.The charge of metal indicated with the Roman numerals and enclosed in the parenthesis after metal name.

3. The ligands are named in alphabetical order before the metal ion.

4. Ligands that include a numerical prefix in the name use the prefixes bis for 2, tris for 3, or tetrakis for 4 to indicate their number.

5. If the complex ion is an anion, we drop the ending of the metal name and add –ate.

In the given coordination compound, Ni is the nickel metal, $Cl$ is the  ligand named as chloro. The charge on coordination sphere is -2.

$x+(-1)4=-2$

$x=+2$

The IUPAC name of $K_2[Ni(Cl)_4]$ is potassium tetrachloro nickeltate (II)
