The video tutorial explains how to balance the chemical equation for the reaction between tetraphosphorus (P4) and oxygen (O2) to form P4O6. It begins by introducing the equation and counting the atoms on both sides. The tutorial then demonstrates how to balance the equation by adjusting the coefficients, specifically placing a '3' in front of O2 to achieve balance. The final balanced equation is presented, and the importance of reporting coefficients is discussed.
