Question

During a reaction, thermal energy from the environment is converted into chemical energy stored in the products. Which of the following can you determine?
A. The reaction is single replacement.
B. The reaction is exothermic.
C. The reaction is endothermic.
D. The reaction is a decomposition.

Answer 1

Answer: The correct answer is Option C.

Explanation:

Thermal energy is defined as the energy present in a system which is possessed by the movement of particles present within a system.

Chemical energy is defined as the energy which is present in the bonds forming a chemical compound.

Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element.

Exothermic reactions are defined as the reactions in which heat is released.

Endothermic reactions are defined as the reactions in which heat is absorbed.

Decomposition reaction is defined as the reaction in which a single large substance breaks down into two or more smaller substances.

According to the question:

When a chemical reaction takes place, thermal energy is getting converted to chemical energy. This means that energy is being absorbed in a chemical reaction.

Thus, the reaction will be endothermic in nature.

Hence, the correct answer is Option C.

Answer 2

Answer:

C. The reaction is endothermic.

Explanation:

An endothermic reaction is a reaction that requires or absorbs energy to take place. This reaction is endothermic because it absorbs thermal energy from the environment.
