Answer 2

Reaction of Magnesium Hydroxide

When magnesium hydroxide reacts with different substances, the following reactions occur:

a) With Potassium Oxide (K2O): - Magnesium hydroxide reacts with potassium oxide to form magnesium oxide and potassium hydroxide. - The balanced chemical equation for this reaction is: ``` Mg(OH)2 + K2O → MgO + 2KOH ```

b) With Nitric Acid (HNO3): - Magnesium hydroxide reacts with nitric acid to form magnesium nitrate and water. - The balanced chemical equation for this reaction is: ``` Mg(OH)2 + 2HNO3 → Mg(NO3)2 + 2H2O ``` c) With Water (H2O): - Magnesium hydroxide is sparingly soluble in water, forming a suspension or solution depending on the concentration. - The reaction can be represented as: ``` Mg(OH)2 + H2O → [Mg(OH)2]n ``` d) With Sodium Nitrate (NaNO3): - Magnesium hydroxide does not have a direct reaction with sodium nitrate under normal conditions.

In summary, magnesium hydroxide reacts with potassium oxide to form magnesium oxide and potassium hydroxide, with nitric acid to form magnesium nitrate and water, and is sparingly soluble in water. However, it does not have a direct reaction with sodium nitrate.
