Chapter 11.2, Problem 17SSC

Interpretation Introduction

Interpretation:

The reason for balancing a chemical equation for solving a stoichiometric problem is to be explained.

Concept introduction:

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.

Answer to Problem 17SSC

A balanced chemical equation is used to determine the relationship between the reactant species and product species in terms of molar ratio.

Explanation of Solution

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 determine the relationship between the reactant species and product species in terms of molar ratio.

Conclusion

A balanced chemical equation is used to determine the relationship between the reactant species and product species in terms of molar ratio.
