To observe a burning candle and calculate the heat associated with the combustion reaction.
Procedure:
1) Measure and record the length of a candle in centimeters.
2) Place the candle on a small piece of aluminum foil and measure the mass of the foil-candle system.
3) Note the time as you light the candle. Let the candle burn for about five minutes.
4) Extinguish the candle and record the time.
5) Measure the mass of the foil-candle system again.
Data:
Analyze and Conclude:
1) 
2) The wick is the one that is burning.
3) The wax is there to hold the wick in place.
4) The air on top of the candle is hotter because heat rises.
5) The candle lost 1.2 centimeters and lost .3 grams. For length it would be mostly the wax and for mass it would be the wick.
6) The wick acts as towel and soaks up the wax. Then the wax and wick burn.
7) C20 H42 30 1/2 O2 ---> 20CO2 + 21H2O
8) 1.16g (1mol/282g) = .00411348 mol
