Balancing Chemical Equations

The video tutorial demonstrates how to balance the chemical equation Na + C yields Na2C2. It begins by counting the number of sodium and carbon atoms on each side of the equation. The tutorial then explains how to balance the equation by adjusting coefficients, ensuring equal numbers of each type of atom on both sides. The process involves placing a coefficient of 2 in front of Na and C to achieve balance. The video concludes with a summary of the balanced equation.
