Respuesta :
Candle wax is made up of several hydrocarbons with the general formula [tex](CH_2)_n[/tex] , where n is a large number.
Hydrocarbon's on reaction with oxygen forms carbon-dioxide and water vapor. This is called combustion reaction.
[tex](CH_2)_n + O_2 \rightarrow CO_2 + H_2O[/tex]
- To find out that carbon-dioxide and water vapor are formed when a candle burns -
- With duct tape, you can secure the candle to the bowl's base.
- Water should be added to the bowl until it reaches the candle's top. Don't let the wick become submerged, please!
- Now you can cover the bowl with transparent lid.
After few minutes, you will observe that the transparent lid is now opaque and there are traces of water deposited on the surface of lid.
Conclusion - the lid is opaque due to the carbon-dioxide formed and water vapors are condensed on the surface of lid.
You can learn more about combustion -
