A balanced chemical reaction is one in which the number of atoms on the left hand side (Reactants) is equal to the number of atoms in the right hand side (Products). Example CH4 + O2 = CO2 +H2O is not balanced because the in the left hand side the number of atoms is 1 + 4 +2 =7 but in the right hand...

https://study.com/academy/lesson/balanced-chemical-equation-definition-examples.html According to the law of conservation of mass, when a chemical reaction occurs, the mass of the products should be equal to the mass of the reactants. Therefore, the amount of the atoms in each element does not change in the chemical reaction. As a result, the chemical equation that shows the chemical reaction needs to be balanced. A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side. read less
