Balance the equation K2O + H2O = KOH using the algebraic method. It's classified as a macronutrient because plants take up large quantities of K during their life cycle. The oxides of potassium react with water vigorously and with enough evolution of heat to cause boiling and spattering of hot caustic solution, [Chemical Safety Data Sheets SD-9, SD-10. One mole of KO2 absorbs 0.5 moles of CO2 and releases 0.75 moles of oxygen. Kingston To Ottawa But these high rates of nutrient removal are not usually being matched with fertilization. Use the crisscross method to check your work.Notes:- Dont write the subscript '1'.- If you use the criss-cross method and end up with something like Ca2S2 you'll need to reduce the subscripts to Ca1S1 which we write CaS.Note: It is possible to have two polyatomic ions such as NH4NO3. Potassium oxide, when heated above \(300\,^\circ {\rm{C}}\), decomposes to form potassium peroxide and potassium. Therefore, K2O is not molecular compound as well.
