Answer:

A.

Step-by-step explanation:

The melting of wax is just a physical change, not a chemical one, since melted wax can still reharden and go back to its original state. All the other choices are non-reversible, chemical changes.

Hopefully this helps- let me know if you have any questions!

Answer:

Melting of candle wax when heated

So what's the difference

  • Physical reaction is reversible
  • Chemical reaction is irreversible

We can get candle wax back when we melted it so it's physical reaction
