Answer 2

Chemical Formulas of Oxides:

The chemical formulas of the given oxides are as follows:

- Aluminum oxide: Al2O3 - Boron (III) oxide: B2O3 - Calcium oxide: CaO - Sulfur (IV) oxide: SO2 - Sodium oxide: Na2O - Phosphorus (V) oxide: P2O5

Formulas of Acidic and Basic Oxides:

Acidic oxides are oxides that react with water to form acids. Basic oxides, on the other hand, react with water to form bases. Let's categorize the given oxides into acidic and basic oxides:

Acidic Oxides: - Boron (III) oxide: B2O3 - Sulfur (IV) oxide: SO2 - Phosphorus (V) oxide: P2O5

Basic Oxides: - Aluminum oxide: Al2O3 - Calcium oxide: CaO - Sodium oxide: Na2O

Reactions of Oxides with Water:

Now, let's discuss the reactions of the given oxides with water:

Boron (III) oxide (B2O3): Boron (III) oxide reacts with water to form boric acid: ``` B2O3 + 3H2O -> 2H3BO3 ``` Sulfur (IV) oxide (SO2): Sulfur (IV) oxide reacts with water to form sulfurous acid: ``` SO2 + H2O -> H2SO3 ``` Phosphorus (V) oxide (P2O5): Phosphorus (V) oxide reacts with water to form phosphoric acid: ``` P2O5 + 3H2O -> 2H3PO4 ``` Aluminum oxide (Al2O3): Aluminum oxide does not react with water.

Calcium oxide (CaO): Calcium oxide reacts with water to form calcium hydroxide (slaked lime): ``` CaO + H2O -> Ca(OH)2 ``` Sodium oxide (Na2O): Sodium oxide reacts with water to form sodium hydroxide: ``` Na2O + H2O -> 2NaOH ```

Please note that the reactions provided above are simplified representations of the reactions between the oxides and water. The actual reactions may involve more complex equilibria and intermediate species.
