Answer 1

Answer:

It is possible to get the wax back after it melts. ... The wax oxidises (burns) in the flame to yield water and carbon dioxide, which dissipate in the air around the candle in a reaction, which also yields light and heat. The unburnt carbon is deposited as a black substance called soot. This signifies a chemical change.
