Balancing Chemical Reactions

The video tutorial demonstrates how to balance the chemical equation CH4 + H2O, which results in carbon monoxide and hydrogen gas. It begins by counting the atoms on both the reactant and product sides, identifying the need to balance the hydrogen atoms. By adjusting the coefficients, the equation is balanced, ensuring equal numbers of each type of atom on both sides. The tutorial concludes with a review of the balanced equation.
