Worksheet for practicing writing chemical formulas, featuring a table with cations and anions and a list of compounds to name.

Problem Overview:

The task involves writing chemical formulas for various compounds based on the given cations and anions. The worksheet provides a table where cations (e.g., zinc, iron (II), etc.) are listed in the top row, and anions (e.g., chloride, acetate, etc.) are listed in the left column. The goal is to determine the correct chemical formula for each compound formed by the intersection of a cation and anion.

Additionally, there is a list of compounds with their names provided, and we need to write their corresponding chemical formulas.

Step-by-Step Solution:

#### Part 1: Completing the Table
To fill in the table, we need to use the charges of the cations and anions to balance the overall charge of the compound to zero. Here are the steps:

1. Identify the charges of the cations and anions:
- Cations:
- Zinc (Zn): +2
- Iron (II) (Fe²⁺): +2
- Iron (III) (Fe³⁺): +3
- Gallium (Ga): +3
- Silver (Ag): +1
- Lead (IV) (Pb⁴⁺): +4
- Anions:
- Chloride (Cl⁻): -1
- Acetate (CH₃COO⁻): -1
- Nitrate (NO₃⁻): -1
- Oxide (O²⁻): -2
- Nitride (N³⁻): -3
- Sulfate (SO₄²⁻): -2

2. Determine the formula for each compound:
- Formula Rule: The total positive charge must equal the total negative charge.
- Use subscripts to balance the charges.

Let's fill in the table:

| | zinc (Zn²⁺) | iron (II) (Fe²⁺) | iron (III) (Fe³⁺) | gallium (Ga³⁺) | silver (Ag⁺) | lead (IV) (Pb⁴⁺) |
|---------|--------------|-------------------|--------------------|-----------------|---------------|-------------------|
| chloride (Cl⁻) | ZnCl₂ | FeCl₂ | FeCl₃ | GaCl₃ | AgCl | PbCl₄ |
| acetate (CH₃COO⁻) | Zn(CH₃COO)₂ | Fe(CH₃COO)₂ | Fe(CH₃COO)₃ | Ga(CH₃COO)₃ | AgCH₃COO | Pb(CH₃COO)₄ |
| nitrate (NO₃⁻) | Zn(NO₃)₂ | Fe(NO₃)₂ | Fe(NO₃)₃ | Ga(NO₃)₃ | AgNO₃ | Pb(NO₃)₄ |
| oxide (O²⁻) | ZnO | FeO | Fe₂O₃ | Ga₂O₃ | Ag₂O | PbO₂ |
| nitride (N³⁻) | Zn₃N₂ | Fe₃N₂ | FeN | GaN | Ag₃N | Pb₃N₄ |
| sulfate (SO₄²⁻) | ZnSO₄ | FeSO₄ | Fe₂(SO₄)₃ | Ga₂(SO₄)₃ | Ag₂SO₄ | Pb(SO₄)₂ |
