(a)
Interpretation: Whether the given figure (a) is of a heterogeneous mixture, a homogeneous mixture or a compound needs to be determined.
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 18A
The given figure is of a heterogeneous mixture.
Explanation of Solution
Substance is made up of the similar types of the atoms. Compound is a substance in which two or more than two different elements are chemically bounded together. The mixture present with a single phase is known as homogeneous and having two or more than two phases is heterogeneous mixture. Heterogeneous mixture is a kind of mixture in which the different parts are not consistently mixed.
A given figure is showing some kind of mixture in which the different parts are not consistently mixed. So, it is heterogeneous mixture.
(b)
