The video tutorial explains how to balance a chemical equation by first counting the number of sulfur and oxygen atoms on each side. Initially, the sulfur atoms are unbalanced, so an 8 is added to balance them. This adjustment affects the oxygen atoms, which are then balanced by placing an 8 in front of the oxygen. The tutorial concludes with a balanced equation, ensuring both sulfur and oxygen atoms are equal on both sides.
