Question

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

Explanation:

Recharging batteries involves a chemical - electrochemical reaction that can be reversed. Rotting of eggs is an irreversible chemical change due to decomposition. Freezing carbon dioxide into dry ice is a physical change (sublimation - deposition is reversible but it's physical). Dehydrating sugar water is a physical change of separating water from sugar by evaporation.

Answer:

recharging batteries
