A balanced equation shows how many moles of each reactant is needed to form a certain number of moles of product. a balance equation must show a subscript change from elements. A balanced chemical equation has the same number of atoms of each element on both sides. The mass of the reactants is equal to the mass of products.
In a balanced chemical equation, both the numbers of each type of atom and the total charge are the same on both sides. Equation 3.9 and Equation 3.10 are balanced chemical equations. What is different on each side of the equation is how the atoms are arranged to make molecules or ions. A chemical reaction represents a change in the distribution of atoms but not in the number of atoms.
