Which of the following example demonstrates the reversibility of a chemical change?(1 point)
dehydrating sugar water
refreezing carbon dioxide gas into dry ice
the rotting of eggs
recharging batteries
ANSWERS
1. dry ice becoming vapor
2. iron (Fe) reacting to water((H2O)
3. conduct a test to determine the chemical makeup of the molecules
4. Atoms of one or more substances rearrange into a new substance.
5. recharging batteries
it was recharging batteries
Apologies for the confusion. The correct answer is recharging batteries. Recharging batteries is a reversible chemical change because it involves converting chemical energy into electrical energy during discharge and then converting electrical energy back into chemical energy during recharge.
