Chapter 2, Problem 8STP

Interpretation Introduction

Interpretation: The figure that represents homogeneous mixture of an element and 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.

Answer to Problem 8STP

Correct answer: Option D and Option C, respectively.

Explanation of Solution

Reason for correct option:

A uniform phase of a mixture is termed as homogeneous mixture. In the homogeneous mixture only similar type of substance (elements or compounds) are present in a single phase, and they cannot be separate easily. According to this, figure D represents a homogeneous mixture of an element and figure C represents a homogeneous mixture of a compound.

Conclusion

Reasons for incorrect options:

Option A: Figure A does not satisfy the condition of homogeneous mixture of an element and a compound. So, this is an incorrect option.

Option B: Figure B does not satisfy the condition of homogeneous mixture of an element and a compound. So, this is an incorrect option.

Option E: Figure E does not satisfy the condition of homogeneous mixture of an element and a compound. So, this is an incorrect option.
