The video tutorial explains how to balance the chemical equation P4 + O2 -> P4O10. It begins by identifying the number of phosphorus and oxygen atoms on each side of the equation. The tutorial then demonstrates how to balance the equation by adjusting the coefficient of O2 to ensure both sides have equal numbers of each type of atom. The final balanced equation is presented, and the tutorial concludes with a brief thank you from Dr. B.
