1. Understand the reactants:
* Potassium oxide (K₂O): This is a basic oxide.
* Nitric acid (HNO₃): This is a strong acid.
2. The reaction:
When a basic oxide reacts with an acid, it forms a salt and water.
3. Products:
* Salt: The salt formed will be potassium nitrate (KNO₃).
* Water: The water will be produced as H₂O.
4. Balanced Chemical Equation:
The balanced chemical equation for the reaction is:
K₂O + 2 HNO₃ → 2 KNO₃ + H₂O
Explanation:
* K₂O + 2 HNO₃: Two moles of nitric acid are needed to react with one mole of potassium oxide.
* 2 KNO₃: Two moles of potassium nitrate are formed.
* H₂O: One mole of water is formed.
Therefore, the chemical formula for the reaction of potassium oxide plus nitric acid is: K₂O + 2 HNO₃ → 2 KNO₃ + H₂O.
