The video tutorial explains how to balance the chemical equation for the decomposition of copper(II) carbonate (CuCO3) into copper(II) oxide (CuO) and carbon dioxide (CO2). It guides viewers through counting the atoms on both sides of the equation, ensuring that the number of each type of atom is equal on both sides. The tutorial highlights common mistakes, such as forgetting to count all oxygen atoms, and concludes with a balanced equation. Dr. B provides a clear and concise explanation, making it easier for viewers to understand the process of balancing chemical equations.
