The example that demonstrates the reversibility of a chemical change is refreezing carbon dioxide gas into dry ice. This process involves a physical change where carbon dioxide gas is converted into a solid state (dry ice) and can be reversed by warming it back into a gas.
The other examples you provided involve either irreversible chemical changes (like the rotting of eggs) or physical changes that are more easily classified (such as dehydrating sugar water, which is more about removing water than a chemical change, and recharging batteries which is a reversible physical change).
