Chapter 2, Problem 17A

(a)

Interpretation Introduction

Interpretation: Gasoline needs to be classified as homogeneous or heterogeneous mixture.

Concept Introduction:Practically all of the matter in environment consists of mixtures of different substance. For example, soil; it has many forms of components, air; it has mixture of many gases, etc.

Answer to Problem 17A

Gasoline is classified as homogeneous mixture.

Explanation of Solution

The mixture present with a single phase is known as homogeneous and having two or more than two phases is heterogeneous mixture. A uniform phase of a mixture is termed as homogeneous mixture. In the homogeneous mixture only similar type of substance are present in a single phase, and they cannot be separate easily.

Gasoline has a uniform composition throughout, and this uniform composition does not separate by the physical method. So, it is homogeneous mixture.

(b)

Interpretation Introduction

Interpretation: A jar of jelly beans needs to be classified as homogeneous or heterogeneous mixture.

Concept Introduction:Practically all of the matter in environment consists of mixtures of different substance. For example, soil; it has many forms of components, air; it has mixture of many gases, etc.

Answer to Problem 17A

A jar of jelly is classified as heterogeneous mixture.

Explanation of Solution

The mixture present with a single phase is known as homogeneous and having two or more than two phases is heterogeneous mixture. A uniform phase of a mixture is termed as homogeneous mixture. In the homogeneous mixture only similar type of substance are present in a single phase, and they cannot be separate easily.

A jar of jelly is a kind of mixture in which the different parts are not consistently mixed. So, it is heterogeneous mixture.

(c)

Interpretation Introduction

Interpretation: Chunky peanuts butter needs to be classified as homogeneous or heterogeneous mixture.

Concept Introduction:Practically all of the matter in environment consists of mixtures of different substance. For example, soil; it has many forms of components, air; it has mixture of many gases, etc.

Answer to Problem 17A

Chunky peanuts butter is classified as heterogeneous mixture.

Explanation of Solution

The mixture present with a single phase is known as homogeneous and having two or more than two phases is heterogeneous mixture. A uniform phase of a mixture is termed as homogeneous mixture. In the homogeneous mixture only similar type of substance are present in a single phase, and they cannot be separate easily.

Chunky peanuts butter is a kind of mixture in which the different parts are not consistently mixed and also a person can pull out the sperate parts from it. So, it is heterogeneous mixture.

(d)

Interpretation Introduction

Interpretation: Margarine needs to be classified as homogeneous or heterogeneous mixture.

Concept Introduction: Practically all of the matter in environment consists of mixtures of different substance. For example, soil; it has many forms of components, air; it has mixture of many gases, etc.

Answer to Problem 17A

Margarine is classified as homogeneous mixture.

Explanation of Solution

The mixture present with a single phase is known as homogeneous and having two or more than two phases is heterogeneous mixture. A uniform phase of a mixture is termed as homogeneous mixture. In the homogeneous mixture only similar type of substance are present in a single phase, and they cannot be separate easily.

Margarine has a uniform composition throughout, and this uniform composition does not separate by the physical method. So, it is homogeneous mixture.

(e)

Interpretation Introduction

Interpretation: The paper needs to be classified as homogeneous or heterogeneous mixture.

Concept Introduction:Practically all of the matter in environment consists of mixtures of different substance. For example, soil; it has many forms of components, air; it has mixture of many gases, etc.

Answer to Problem 17A

The paper on which this question is printed, classified as homogeneous mixture.

Explanation of Solution

The mixture present with a single phase is known as homogeneous and having two or more than two phases is heterogeneous mixture. A uniform phase of a mixture is termed as homogeneous mixture. In the homogeneous mixture only similar type of substance are present in a single phase, and they cannot be separate easily.

Paper has a uniform composition throughout, and this uniform composition does not separate by the physical method. So, it is homogeneous mixture.
