The video tutorial explains how to balance the chemical equation for zinc and iron(III) chloride. It begins by counting the atoms on both sides of the equation and adjusting coefficients to balance chlorine atoms. The tutorial then balances zinc and iron atoms, resulting in a balanced equation. The type of reaction is identified as a single displacement reaction, where zinc displaces iron due to its higher position in the activity series.
