The video tutorial demonstrates how to balance a chemical equation involving calcium phosphate and carbon, resulting in calcium phosphide and carbon monoxide. It begins by identifying the components of the equation, then counts the atoms on both sides. The tutorial proceeds to adjust the coefficients to balance the equation, ensuring the number of atoms for each element is equal on both sides. The process is explained step-by-step, highlighting the importance of balancing chemical equations in chemistry.
