Concept introduction: The stoichiometric number is defined as the digit that is written in front of any molecule, atom or ion that is taking part in a chemical reaction.

Answer to Problem 1RQ
A balanced chemical equation is used to determine the stoichiometric mixture in a chemical reaction.
Explanation of Solution
According to law of conservation of mass it is not possible to form the mass or to destroy the mass. The mass always remains conserved. The balancing of chemical equation equalizes the number of atoms of each element at the reactant side as well as at the product side. Thus, this balancing ultimately makes the mass of each species equal on both the sides of the chemical equation. Therefore, balanced chemical equation can be used to recognize stoichiometric mixture in a chemical reaction.
