Balanced chemical equations provide: the exact quantities of the reactants and products information about how fast the reaction will proceed ratios of atoms, ions, molecules and/or formula units used in the equation an outline of how the substances change from reactants to

ratios of atoms, ions, molecules and/or formula units used in the equation

Explanation:

Symbolic representation of the chemical reaction with the help of the formulas and symbols is known as chemical equation. In the chemical equation, reactants are written at left-hand side as well as products are expressed or written on right-hand side. The coefficients which are written before the formulas or the symbols are known as stoichiometric numbers.

The balanced chemical equation shows the exact number of moles of the reactants which are equal to the moles of the products.

For example:-

The balanced combustion reaction of the oxidation of propane is shown below as:-

Thus, Balanced chemical equation tells the stoichiometry of the reaction which is ratios of atoms, ions, molecules and/or formula units used in the equation.
