What is the chemical equation for potassium oxide and water?

The chemical equation for the reaction between potassium oxide (K2O) and water (H2O) is:

K2O + H2O → 2KOH

In this reaction, potassium oxide reacts with water to form potassium hydroxide. The potassium oxide molecule (K2O) reacts with water (H2O) to produce two molecules of potassium hydroxide (2KOH).
