Chapter 7, Problem 1SAQ

Which process is a chemical reaction?

a. Gasoline evaporating from a gasoline tank

b. Iron rusting when left outdoors

c. Dew condensing on grass during the night

d. What boiling on a stove top

Expert Solution & Answer

Interpretation Introduction

Interpretation: Amongst the given processes, a chemical reaction is to be identified.

Concept Introduction: The chemical reaction involves a chemical change. Moreover, it is a process that includes rearrangement of ionic or molecular structure of a substance. The chemical reaction can be simple or complex.

Answer to Problem 1SAQ

Correct Answer: The rusting of iron when left outdoors is a chemical reaction.

Therefore, option (b) is correct.

Explanation of Solution

Reason for correct option:

The rusting of iron is an oxidation reaction. It involves oxidation of iron in the presence of oxygen and water. Moreover, in the process of rusting, iron reacts with the oxygen present in the air and forms iron oxide.

Hence, option (b) is correct.

Reasons for incorrect options:

Option (a) is incorrect because evaporation of gasoline from a gasoline tank is an example of evaporation, which is a physical process. Thus, it is a wrong answer.

Option (c) is incorrect because the dew (tiny water droplets) that appears on the grass is due to the process of condensation, which is a physical process. Thus, it is a wrong answer.

Option (d) is incorrect because the process of boiling of water is due to the heating effect. Boiling is a physical process. Thus, it is a wrong answer.

Hence, options (a), (c), and (d) are incorrect.
