**Question:**

Write the empirical formula for at least four ionic compounds that could be formed from the following ions:

\[ \text{CO}_3^{2-}, \, \text{MnO}_4^{-}, \, \text{Fe}^{2+}, \, \text{NH}_4^{+} \]

**Answer Box:**
```

```

**Explanation:**

You are given a set of ions with their charges:

- Carbonate ion: \( \text{CO}_3^{2-} \)
- Permanganate ion: \( \text{MnO}_4^{-} \)
- Iron(II) ion: \( \text{Fe}^{2+} \)
- Ammonium ion: \( \text{NH}_4^{+} \)

Using these ions, you need to form ionic compounds by combining cations and anions in such a way that the total charge of the compound is zero. Below are four possible combinations:

1. **Iron(II) Carbonate:**
   - \( \text{Fe}^{2+} \) and \( \text{CO}_3^{2-} \)
   - Empirical Formula: \( \text{FeCO}_3 \)

2. **Iron(II) Permanganate:**
   - \( \text{Fe}^{2+} \) and \( 2\text{MnO}_4^{-} \)
   - Empirical Formula: \( \text{Fe(MnO}_4\text{)}_2 \)

3. **Ammonium Carbonate:**
   - \( 2\text{NH}_4^{+} \) and \( \text{CO}_3^{2-} \)
   - Empirical Formula: \( \text{(NH}_4\text{)}_2\text{CO}_3 \)

4. **Ammonium Permanganate:**
   - \( \text{NH}_4^{+} \) and \( \text{MnO}_4^{-} \)
   - Empirical Formula: \( \text{NH}_4\text{MnO}_4 \)

Ensure to balance the charges properly to form neutral compounds when writing the empirical formula.
