The video tutorial explains how to balance a chemical equation involving carbon monoxide and hydrogen gas to produce methane and water. It begins by identifying the reactants and products, then counts the atoms on each side of the equation. The tutorial demonstrates how to balance the equation by adjusting coefficients, ensuring the number of atoms for each element is equal on both sides. Common mistakes, such as forgetting to count all hydrogen atoms, are addressed. The video concludes with a balanced equation and a thank you from Dr. B.
