Balancing Chemical Equations and Products

The video tutorial explains how to balance the chemical equation CO + H2 → CH3OH. It begins by counting the atoms on each side of the equation, identifying that the hydrogen atoms are unbalanced. The tutorial then demonstrates how to balance the hydrogen atoms by adjusting the coefficients, specifically by placing a coefficient of 2 in front of H2. This adjustment ensures that the number of hydrogen atoms is equal on both sides, resulting in a balanced equation. The video concludes with a confirmation that the equation is balanced, yielding methanol as the product.
