The chemical aspect: oxygen O 2 and paraffin C n H 2n+2 react. The burning produces water H 2 O and carbon dioxide C O 2. For n=1 we balance the equation as follows: 2 O 2 + C H 4 = C O 2 + 2 H 2 O. Because twice as much oxygen is burned than carbon dioxide released, the air volume decreases.oxygen candles candles oxygen Prior art date 1979-04-04 Legal status (The legal status is an assumption and is not a legal conclusion.

O 2 has a bond length of 121 pm and a bond energy of 498 kJ/mol.. Triatomic oxygen (Ozone, O 3), the less common triatomic allotrope of oxygen, is a poisonous gas with a distinctive odor.A candle flame is formed because wax vaporizes on burning. A candle flame is widely recognized as having between three and five regions or "zones": Zone I - this is the non-luminous, lowest, and coolest part of the candle flame. It is located around the base of the wick where there is insufficient oxygen for fuel to burn.Complete Combustion: Also called "clean combustion," complete combustion is the oxidation of a hydrocarbon that produces only carbon dioxide and water.An example of clean combustion would be burning a wax candle: The heat from the flaming wick vaporizes the wax (a hydrocarbon), which in turn, reacts with oxygen in the air to release carbon dioxide and water.When someone is exposed to carbon monoxide gas, the gas molecules of CO displaces the oxygen in the person's body, leading to poisoning. ...
