Balancing Chemical Equations

The video tutorial explains how to balance the chemical equation NaI + Cl2. It begins by identifying the number of each type of atom on both sides of the equation. The tutorial then demonstrates how to balance the chlorine atoms by adding a coefficient of 2 in front of NaCl, followed by balancing the sodium and iodine atoms by adding a coefficient of 2 in front of NaI. The video concludes with the final balanced equation: 2 NaI + Cl2 = 2 NaCl + I2.
