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

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

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.
