![**Exercise: Empirical Formula for Ionic Compounds**
Instructions: Write the empirical formula for at least four ionic compounds that could be formed from the following ions:
- \( \text{Fe}^{3+} \)
- \( \text{CrO}_4^{2-} \)
- \( \text{Pb}^{4+} \)
- \( \text{PO}_4^{3-} \)
**Answer the question below:**
[Space for answer]
**Hints:**
- To form a neutral compound, the total positive charge must equal the total negative charge.
- Combine the ions in the smallest ratio that balances the charges.
