Melted Wax a Physical Change Igniting The White Smoke

C25H52 + O2 ----->Using Energy in the Form of Fire----> CO + C + H2 + H2O

This is a basic explanation and the chemical equation is not balanced, but it is fine for now.
Candle Wax + Oxygen in Air--------> Carbon Monoxide + Black Carbon + Hydrogen + Water
White Smoke = Hydrogen Black Carbon Does Not Ignite Igniting the White Smoke
