Question

Which of the following statements correctly describe the primary uses of the chemical reactions of gasoline?

A)Gasoline undergoes combustion in internal combustion engines to produce mechanical energy.
B)Gasoline reacts with oxygen to release energy for electricity generation.
C)Gasoline is used as a raw material in the production of plastics.
D)Gasoline participates in redox reactions to produce heat for residential heating.
E)Gasoline undergoes combustion in power plants to generate steam.

Answer 1

The correct statement about the primary use of gasoline's chemical reactions is A) Gasoline undergoes combustion in internal combustion engines to produce mechanical energy. Gasoline's chemical energy becomes kinetic energy, powering vehicles for transportation.

Step-by-step explanation:

The primary uses of the chemical reactions of gasoline are predominantly centered around energy transformation through the process of combustion. Through this reaction, the chemical energy stored within gasoline's hydrocarbon molecules is converted to kinetic energy, which is necessary to power internal combustion engines.

A) is correct: Gasoline undergoes combustion in internal combustion engines to produce mechanical energy. Gasoline and oxygen react to release energy, which then powers vehicles. The engines of cars transform the chemical energy of gasoline into kinetic energy, allowing them to move efficiently between locations such as home, work, and school.

On the other hand, while combustion reactions do generate energy, options B, C, D, and E suggest incorrect or less common uses for gasoline. For instance, gasoline is not usually a raw material in plastic production, nor is it primarily used for residential heating or electricity generation in power plants through steam.
