Classification of Compounds and Naming

To classify and name the given compounds, let's first understand the different types of compounds mentioned:

1. Oxides: Oxides are compounds that contain oxygen bonded to another element. They can be further classified into acidic oxides and basic oxides. 2. Acids: Acids are compounds that release hydrogen ions (H+) when dissolved in water. They are typically composed of hydrogen and a non-metal or polyatomic ion. 3. Bases: Bases are compounds that release hydroxide ions (OH-) when dissolved in water. They are typically composed of a metal cation and a hydroxide ion. 4. Salts: Salts are compounds formed by the reaction between an acid and a base. They are composed of a metal cation and a non-metal anion.

Now, let's classify and name the given compounds:

1. CaO: - Classification: This compound is an oxide. - Name: Calcium oxide.

2. C: - Classification: This compound is an element. - Name: Carbon.

3. HNO3: - Classification: This compound is an acid. - Name: Nitric acid.

4. SiO2: - Classification: This compound is an oxide. - Name: Silicon dioxide.

5. Fe(OH)2: - Classification: This compound is a base. - Name: Iron(II) hydroxide.

6. K: - Classification: This compound is an element. - Name: Potassium.

7. K2CO3: - Classification: This compound is a salt. - Name: Potassium carbonate.
