The video tutorial demonstrates how to balance the chemical equation F2 + PF4 = PF3. It begins by counting the atoms of fluorine and phosphorus on both sides of the equation. The instructor then adjusts the coefficients to balance the phosphorus atoms, followed by the fluorine atoms. The final balanced equation is presented, ensuring equal numbers of each type of atom on both sides.
