Chapter 11, Problem 55A

Interpretation Introduction

Interpretation:

The type of information provided by the balance equation needs to be explained.

Concept introduction:

The stoichiometric calculations are based on mole concept. The mole concept provides the relation between moles, mass and molar mass. The mathematical expression of mole concept can write as:

$\text{Mole =}\frac{\text{Mass}}{\text{Molar mass}}$

Answer to Problem 55A

The balance chemical equation provides the mole ratio of reactant and product molecules.

Explanation of Solution

The stoichiometric calculations are based on different steps like calculation of mass and moles, interpret the mole ratio and further calculate of mass of desired product.

The first step of all the stoichiometric calculations is writing the balance chemical equation for the given chemical reaction as balance chemical equation provide idea about the mole ratio of reactant and product molecules. The coefficients of reactant and product molecules show the mole ratio of them.

Conclusion

The balance chemical equation provides the mole ratio of reactant and product molecules.
