Balancing Chemical Equations

In this video, Dr. B demonstrates how to balance the chemical equation Cl2 + I2 yields ICl3. The process involves counting the chlorine and iodine atoms on both sides of the equation and adjusting coefficients to ensure the number of atoms is equal on both sides. By applying a coefficient of 2 to ICl3 and adjusting the coefficients of Cl2 and I2, the equation is successfully balanced. The video concludes with a confirmation of the balanced equation.
