The video tutorial explains how to balance the chemical equation of sodium peroxide reacting with water. It begins by identifying the reactants and products, then counts the atoms on each side of the equation. The tutorial demonstrates balancing the equation by adjusting coefficients to ensure the number of each type of atom is equal on both sides. The process involves careful counting and adjustment of sodium, oxygen, and hydrogen atoms. The video concludes with a balanced equation and a brief summary of the steps taken.
