Wax is a hydrocarbon. When the wick is lit, the solid wax melts and becomes a liquid. This liquid soaks into the wick and in the heat it is vaporized. The flame is a zone of combustion of these vapours of wax. When a candle burns, the carbon from the wax combines with oxygen in the air. Carbon undergoes oxidation, and gets changed into carbon dioxide. At the same time hydrogen combines with air to form water vapours. Some of the carbon does not burn and is deposited as soot.
