Chapter 2, Problem 1STP
Interpretation Introduction

Interpretation: The option that does not represent a chemical change should be identified.

Concept Introduction: In a chemical change, the chemical bonds present in reactants are broken to form elements that are then rearranged to form new chemical bonds resulting in the formation of products that possess different compositions than the reactants.

Expert Solution & Answer

Answer to Problem 1STP

Correct answer: Paper being shredded.

Explanation of Solution

Reason for correct option:

During shredding a paper, only the appearance of the paper changes, and the chemical composition of the paper does not change. Since the chemical composition of paper remains the same, it is not a chemical change. Instead, it is a physical change.

Conclusion

Reasons for incorrect options:

Steel rusting, charcoal burning, and a newspaper yellowing in the sun are examples of chemical change as the chemical compositions are different from the initial substance and reactants. A completely new matter is obtained after steel rusting, charcoal burning, and a newspaper yellowing in the sun.
