The video tutorial explains the process of balancing a chemical equation involving methane (CH4) and chlorine gas (Cl2) to produce dichloromethane (CH2Cl2) and hydrochloric acid (HCl). It begins by introducing the reactants and products, followed by counting the atoms of each element. The tutorial then demonstrates how to balance the hydrogen atoms by adjusting coefficients and proceeds to balance the chlorine atoms. The video concludes with the final balanced equation and a brief summary.
