(a) Interpretation: An explanation regarding the shape of the given graph is to be stated. Concept Introduction: A reactant that would be eliminated first if the reaction proceeded to completion is known as the limiting reactant. In other words, it is the reactant that is present in the lower concentration in the given reaction mixture. The other reactant that is present in higher concentration in the given reaction mixture is known as the excess reactant.

Solutions

Chapter 9, Problem 18ALQ
Interpretation Introduction

(a)

Interpretation:

An explanation regarding the shape of the given graph is to be stated.

Concept Introduction:

A reactant that would be eliminated first if the reaction proceeded to completion is known as the limiting reactant. In other words, it is the reactant that is present in the lower concentration in the given reaction mixture. The other reactant that is present in higher concentration in the given reaction mixture is known as the excess reactant.

Interpretation Introduction

(b)

Interpretation:

The mass of NaCl that is formed after using 20.0g of sodium is to be calculated.

Concept Introduction:

A reactant that would be eliminated first if the reaction proceeded to completion is known as the limiting reactant. In other words, it is the reactant that is present in the lower concentration in the given reaction mixture. The other reactant that is present in higher concentration in the given reaction mixture is known as the excess reactant.

Stoichiometry helps in determining the relationship between the number of moles of the reactants and products that are involved in a reaction. For proper calculations, the reaction must be balanced.

Interpretation Introduction

(c)

Interpretation:

The mass of Cl2 that is present in each container is to be calculated.

Concept Introduction:

A reactant that would be eliminated first if the reaction proceeded to completion is known as the limiting reactant. In other words, it is the reactant that is present in the lower concentration in the given reaction mixture. The other reactant that is present in higher concentration in the given reaction mixture is known as the excess reactant.

Stoichiometry helps in determining the relationship between the number of moles of the reactants and products that are involved in a reaction. For proper calculations, the reaction must be balanced.

Number of moles is equal to the ratio of given mass to the molar mass.

Interpretation Introduction

(d)

Interpretation:

The mass of NaCl that is formed after using 50.0g of sodium is to be calculated.

Concept Introduction:

A reactant that would be eliminated first if the reaction proceeded to completion is known as the limiting reactant. In other words, it is the reactant that is present in the lower concentration in the given reaction mixture. The other reactant that is present in higher concentration in the given reaction mixture is known as the excess reactant.

Stoichiometry helps in determining the relationship between the number of moles of the reactants and products that are involved in a reaction. For proper calculations, the reaction must be balanced.

Number of moles is equal to the ratio of given mass to the molar mass.

Interpretation Introduction

(e)

Interpretation:

The leftover reactant in the given reaction is to be identified. The mass of the leftover reactant for parts b and d is to be calculated.

Concept Introduction:

A reactant that would be eliminated first if the reaction proceeded to completion is known as the limiting reactant. In other words, it is the reactant that is present in the lower concentration in the given reaction mixture. The other reactant that is present in higher concentration in the given reaction mixture is known as the excess reactant.

Stoichiometry helps in determining the relationship between the number of moles of the reactants and products that are involved in a reaction. For proper calculations, the reaction must be balanced.
