(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.

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: Chunky peanuts butter 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.
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.
