The video tutorial explains how to balance a chemical equation involving NaF and CaBr2, a double displacement reaction. It begins by counting the atoms on each side of the equation, identifying imbalances in fluorine and bromine atoms. The tutorial then demonstrates how to balance these atoms by adjusting coefficients, ensuring the same number of each type of atom on both sides. The process concludes with a balanced equation, highlighting the importance of balancing chemical reactions.
