activity 1 1-18-11 Burning Candle Observation

What is burning? Show the chemical formula and an image of the structure.
The wick pulls the wax out of the candle and through the wick.


Write the chemical reaction.
 
When you burn a candle, you are performing simple combustion reactions of this type. The oxygen comes from the air and the heat initially comes from an outside source such as a match. When this combustion reaction happens, it makes water and carbon dioxide as shown as well as heat and light energy. The coefficients tell us how much of each component is used and produced.
 
Write the balanced chemical reaction.
C25H52 + 38 O2 ------- 25CO2 + 26 H2O + energy (heat and light)

butane O2   O
