Balanced Equations

Definition

A balanced equation is a chemical equation in which the number of atoms of each element is the same on both the reactant and product sides, ensuring that matter is conserved during the chemical reaction. This concept is crucial in the context of solving equations using the subtraction and addition properties of equality.
