of combustion of paraffin (candle wax) by burning a candle and holding a calorimeter (a soda can) filled with 98.7 mL of water above the flame. The heat released by the candle was absorbed by the water in the can. It was important to place the metal chimney around the candle so that minimal amounts of heat would escape; having too much heat lost to the atmosphere would cause extra error in the calculations. The assumption made was that all heat released from the candle was absorbed by the water‚

this lab I observed the burning of a candle very closely. I found out that the candle needs oxygen to burn‚ that it produces carbon dioxide similar to the way that my body produces carbon dioxide‚ and that a candle produces water as a second waste product. I learned that if I hold an object in the flame it becomes covered with soot which is unburned carbon fuel. Finally‚ I learned that neither the solid wax‚ nor the melted wax‚ nor the wick burns when a candle is lit. In fact‚ the wax itself is burning

Baking soda has a natural cleansing ability and can even be found in some commercial toothpastes. It’s non-toxic and will help polish your teeth. Some recipes call for table salt‚ in which case you should mix three

Mass of the candle was measured before proceeding to further steps. 100 mL of chilled water‚ which is 10-15 ºC colder than the room temperature‚ was prepared and was poured into the empty can. An apparatus was installed with a stand and a holder. The can was placed hanging on the stand by a glass rod (the rod went through the hole of can’s handle (?) and was placed above the holder). The candle was installed right below (about 2cm below) the can. The room temperature and the water temperature were

Case 7 1. What kind of strategy would small businesses like these candlemakers choose when competing with a mass-market competitor like Yankee candle? I think they should use the Focus Strategy. Why that approach? Just focus on the group of people you are targeting not on all consumers. Yankee Candles will promote and target both men and female with all their scents. So if you only carry scents for men then I would target women‚ men‚ children‚ etc. who are buying an unique gift

characteristics of a candle flame? What are the products of the combustion of a candle? The purpose of this lab was to find out the properties and characteristics of a candle. Also the purpose was to find the remnants that the combustion of a candle leaves behind as gas. I learned that the candle that is burning releases a certain gas into the air. I also learned that limewater has a chemical reaction when exposed to that gas and turns red. Hypothesis: For this Lab‚ my hypothesis was that the candles are going

As “equal rights of all men” changed from the equal rights of rich white men‚ to all white men‚ to men and women the ballot range has gotten larger and larger.
