Balanced Chemical Reaction

A balanced chemical reaction is a chemical equation that has the same number of atoms of each element on both sides of the equation:
The number of atoms for each element is the same on the reactant side and the product side
The total charge is the same on both sides of the reaction
The mass of the reactants is equal to the mass of the products
How to Balance Chemical Equations: 11 Steps (with Pictures)
A balanced chemical equation is consistent with the law of conservation of mass and constant proportions.
To balance a chemical equation, you can:
Write down the unbalanced equation
Determine if the equation is already balanced
If not balanced, start by balancing the elements that appear in the lowest number of reactant and product molecules
Balance the remaining elements
Make sure the number of atoms in each element is balanced
You can also multiply each side of the equation by the same number if a molecule has a fractional value.
Balanced equations often include state symbols in brackets after each formula. These symbols indicate the physical state of the substance. For example, (s) indicates solid, (l) indicates liquid, (g) indicates gas, and (aq) indicates an aqueous solution
