Chapter 2, Problem 2STP

Interpretation Introduction

Interpretation: Whether apple is a heterogeneous mixture, a heterogenous substance, a homogenous compound or a homogenous mixture needs to be identified.

Concept Introduction: Substances made up of two or more elements chemically combined are called compounds. On the other hand, mixtures are formed by mixing two or more substances physically.

Answer to Problem 2STP

Correct option is (A).

Explanation of Solution

Reason for correct option:

In heterogeneous mixtures, the components of the mixture can be easily identified. There is more than one phase that can be seen by the naked eye. It has a non-uniform composition.

In apples, there are visible different components such as apple slices and seeds that can be seen by the naked eye. Thus, the apple is said to be a heterogeneous mixture.

Thus, option (A) is correct.

Conclusion

Reason for incorrect options:

The homogenous compound has the same proportion of elements throughout. All compounds are homogenous.

Heterogenous substances have different or distinguishable elements. They have more than one phase of matter.

A mixture in solid, liquid, or gaseous form is said to be homogenous if it has the same proportions of components throughout the sample. Thus, in any homogenous mixture, only one phase of matter is observed.

Since, apple is not a compound and elements are not present in any particular proportion, options (B), (C) and (D) are incorrect.
