This video tutorial demonstrates how to balance the chemical equation for the decomposition of lithium chlorate (LiClO3) into lithium chloride (LiCl) and oxygen (O2). The instructor explains the process of counting atoms on both sides of the equation, focusing on balancing the oxygen atoms by making them even. By applying coefficients, the equation is balanced, ensuring the same number of each type of atom on both sides. The tutorial concludes with a balanced equation for the decomposition reaction.
