Answer:
Magnesium reacts with steam to form magnesium oxide and water.
Potassium oxide + water produces potassium hydroxide. Potassium oxide is an ionic compound. The potassium has a charge of K+ and oxygen has a charge of O2− . We need 2 potassium ions to balance one oxide ion making the formula K2O .
