Concept introduction:
- Balanced chemical equation of a reaction is written according to law of conservation of mass.
- Equation for Number of moles of a substance, from its given mass is,
- Mole ratio between the reactant and a product of a reaction are depends upon the coefficients of reactant and product in a balanced chemical equation.

Answer to Problem 3.111QP
The fraction of
Explanation of Solution
In given reaction,
Mixture of
Therefore,
The chemical equation for this reaction is,
Balanced chemical equation of a reaction is written according to law of conservation of mass.
Therefore,
The total number of each atoms in the reactant side should equal to the total number of each atoms in the product side.
So, in order to balance a chemical equation, the coefficients of compounds or atoms are needed to be changed in such a way that total number of each atoms in the reactant side and the total number of each atoms in the product side is to become equal.
Hence,
The balanced equations for the given reactions are,
Assumes mass of
The mass of Mixture of
Let’s take mass of
So, the number of moles of
The balanced chemical equation of the reaction is,
The mole ratio between
The mole ratio between
So, the number of moles of
