Explanation

To write the formulas for the given coordination compounds using IUPAC nomenclature, we will follow these steps for each compound:

### Step-by-Step Solutions:

1. **Tetrahydroxozincate(II)**
- Identify the central metal ion: Zinc (Zn).
- Determine the oxidation state: (II) indicates +2.
- Identify the ligands: Tetrahydroxo means there are four hydroxide (OH) ligands.
