The method used to balance a chemical equation is called the trial and error method. In this method, we count the number of atoms of the reactants and products and adjust the coefficients in front of the chemical formulas to balance the equation. To make the process easier, we can start by balancing the metals, then the non-metals, followed by oxygen, and finally hydrogen.
