Let's analyze the table in your image and fill in the missing empirical formulas and names of compounds:

### Cation and Anion Pairs

1. **Sodium (Na⁺) + Acetate (CH₃CO₂⁻)**:
   - **Empirical formula**: Sodium ion (Na⁺) and acetate ion (CH₃CO₂⁻) combine in a 1:1 ratio since both have charges of +1 and -1.
   - **Formula**: NaCH₃CO₂
   - **Name**: Sodium acetate

2. **Iron (Fe³⁺) + Carbonate (CO₃²⁻)**:
   - **Empirical formula**: To balance the charges between Fe³⁺ (3+) and CO₃²⁻ (2-), you need two Fe³⁺ ions and three CO₃²⁻ ions, giving the empirical formula Fe₂(CO₃)₃.
   - **Name**: Iron(III) carbonate

3. **Sodium (Na⁺) + Iodate (IO₃⁻)**:
   - **Empirical formula**: Sodium ion (Na⁺) and iodate ion (IO₃⁻) combine in a 1:1 ratio since both have charges of +1 and -1.
   - **Formula**: NaIO₃
   - **Name**: Sodium iodate

### Summary of Answers

| **Cation** | **Anion**   | **Empirical Formula** | **Name of Compound**   |
|------------|-------------|-----------------------|------------------------|
| Na⁺        | CH₃CO₂⁻     | NaCH₃CO₂              | Sodium acetate         |
| Fe³⁺       | CO₃²⁻       | Fe₂(CO₃)₃             | Iron(III) carbonate     |
| Na⁺        | IO₃⁻        | NaIO₃                 | Sodium iodate          |
