The video tutorial explains how to balance a chemical equation involving copper carbonate and nitric acid. It begins by counting the atoms on both the reactant and product sides of the equation. The tutorial then demonstrates balancing the equation by adjusting coefficients, focusing on balancing nitrogen and hydrogen atoms first, followed by oxygen atoms. The process concludes with a balanced equation, ensuring all atoms are accounted for on both sides.
