Candle Chemistry

Candles represent a classic example of the process of combustion. When enough heat is applied, the wax of a candle starts to oxidize. The paraffin reacts with oxygen to produce carbon dioxide and water, and also heat and light. The flame is the visible part of this exothermic reaction - where the reaction is energetic enough to produce visible light. Here are some more facts about candles:
