Which of the following example demonstrates the reversibility of a chemical change?(1 point)

Question

Responses

recharging batteries

dehydrating sugar water

refreezing carbon dioxide gas into dry ice

the rotting of eggs

Answer 1

The example that demonstrates the reversibility of a chemical change is "recharging batteries."

During the recharging process, the chemical reactions that occur in the battery when it is discharged are reversed. Essentially, the electrical energy supplied to recharge the battery is converted back into chemical potential energy stored within the battery. This is a common example of a reversible chemical change.

The other examples listed are not reversible through simple chemical means:

- Dehydrating sugar water is a physical process of removing water; while the water can be added back to sugar, the process itself isn't a chemical change.
- Refreezing carbon dioxide gas into dry ice is a change of state from gas to solid, which is a physical change, not a chemical one.
- The rotting of eggs is an irreversible chemical change where the organic material decomposes into various simpler substances due to chemical reactions, typically not reversible.

Answer 2

what is the correct answer

Answer 3

I apologize for any confusion. The correct answer that demonstrates the reversibility of a chemical change is "recharging batteries." This is because recharging a battery involves reversing the chemical reactions that occur during its discharge, thereby restoring the reactants to their original state and re-storing the energy within the battery for future use. This is a clear example of a reversible chemical change.
