Dear Student
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
e.g :
The 3 characteristics of balanced equation is :
1) We can get equal no. of atoms on both the sides.
2) weight of products and reactants remains constant
3) Desired stoichiometry of the reactant and product is determined to calculate the required amount of reactant and desired result of product.
