What are the Molecular formulas for water and hydrogen peroxide?
Water is H2O Hydrogen Peroxide is H2O2 I hope you found this useful.
Water is H2O. Hydrogen peroxide is H2O2. Hydrogen peroxide has one more oxygen atom per molecule than water. The extra oxygen is what makes it a peroxide. "Hydrogen oxide" would be water. The extra oxygen also makes hydrogen peroxide much more reactive than water due to the unstable oxygen-oxygen bond.
