After the candle goes out, students are told that it used upthe oxygen in the jar, as though oxygen were a type of food thecandle ate until there was none left.While the ï¬ameâs death certainly indicates a linkage betweenï¬re and oxygen, the accompanying narrative is rather off.
In this lab we did a series of experiments to explore the chemical reaction: Fuel + O2 (CO2 + H2O where the fuel is a candle. This reaction is a combustion reaction. We found that the candle does in fact need oxygen to burn because when we cut off the supply of fresh air with a beaker, the candle went out. This happened because the burned candle used up the oxygen inside the beaker and new oxygen from the air couldnât get to it.
