Which of the following example demonstrates the reversibility of a chemical change?(1 point) Responses dehydrating sugar water dehydrating sugar water refreezing carbon dioxide gas into dry ice refreezing carbon dioxide gas into dry ice recharging batteries recharging batteries the rotting of eggs

Answer 1

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

Here’s why:

• Dehydrating sugar water involves a physical change (removal of water), and reconstituting it is a physical process.
• Refreezing carbon dioxide gas to create dry ice is also a physical change (gas to solid).
• The rotting of eggs is a chemical change where new substances are formed, and this process is not reversible.

In contrast, recharging batteries involves the chemical reactions within the battery being reversed, allowing the battery to return to its charged state, making it an example of a reversible chemical change.
