Answer 1

Using IUPAC nomenclature for coordination compounds:
1. [Cu(NH\(_3\))\(_4\)]Cl:
- Ligand: NH\(_3\) (ammine), neutral.
- Metal: Cu, oxidation state +1 (since Cl\(^-\) balances +1 charge).
- Name: Tetraamminecopper(I) chloride.
2. [Pt(NH\(_3\))\(_4\)]Cl\(_2\):
- Ligand: NH\(_3\) (ammine), neutral.
- Metal: Pt, oxidation state +2 (since 2 Cl\(^-\) balance +2 charge).
- Name: Tetraammineplatinum(II) chloride.
Answer: Tetraamminecopper(I) chloride and tetraammineplatinum(II) chloride.
