Matching Formulas with Compound Classes:

To match the formulas with their corresponding compound classes, we need to analyze the properties and characteristics of each compound. Let's go through each compound one by one:

1. HF: - This compound is hydrofluoric acid. - It is a two-acidic acid because it can donate two hydrogen ions (H+) when dissolved in water. - Therefore, it belongs to the class of two-acidic acids.

2. NaOH: - This compound is sodium hydroxide. - It is a soluble base because it readily dissolves in water to produce hydroxide ions (OH-). - Therefore, it belongs to the class of soluble bases.

3. Fe(OH)3: - This compound is iron(III) hydroxide. - It is a soluble base because it readily dissolves in water to produce hydroxide ions (OH-). - Therefore, it belongs to the class of soluble bases.

4. Cl2O7: - This compound is dichlorine heptoxide. - It is a acidic oxide because it reacts with water to form an acid. - Therefore, it belongs to the class of acidic oxides.

5. H2CO3: - This compound is carbonic acid. - It is a two-acidic acid because it can donate two hydrogen ions (H+) when dissolved in water. - Therefore, it belongs to the class of two-acidic acids.

6. CuO: - This compound is copper(II) oxide. - It is a basic oxide because it reacts with water to form a base. - Therefore, it belongs to the class of basic oxides.

7. AgCl: - This compound is silver chloride. - It is a soluble salt because it readily dissolves in water to form ions. - Therefore, it belongs to the class of soluble salts.

8. Na2CO3: - This compound is sodium carbonate. - It is a soluble salt because it readily dissolves in water to form ions. - Therefore, it belongs to the class of soluble salts.

9. H3PO4: - This compound is phosphoric acid. - It is a three-acidic acid because it can donate three hydrogen ions (H+) when dissolved in water. - Therefore, it belongs to the class of three-acidic acids.

Summary:

- HF: Two-acidic acid - NaOH: Soluble base - Fe(OH)3: Soluble base - Cl2O7: Acidic oxide - H2CO3: Two-acidic acid - CuO: Basic oxide - AgCl: Soluble salt - Na2CO3: Soluble salt - H3PO4: Three-acidic acid
