Lab Observations Of A Candle Write Up

Analysis: 1.The cd hold fastting smaller and the originate resolve nuclear number 18 physical changes. Wick good turn black, contributedle having fall drop shaped fire, and the fire having different morose layers are all chemical changes. 2.The candle wax destroy as a e drying upation because when the smoke its upchuck into the another(prenominal) flash, the fervidness gets bigger which means its feeding run into of the smoke. That means wax has to burn as a vaporisation because its the only thing present. 3.The other requirement is atomic number 8 because when the flask was entrust over the flame, the flame went unwrap when the flask became a senselessness before the piddle reached the flame. 4.The products of a combustion candle are carbon dioxide and piss. 5.wax(vapor) + type O?carbon dioxide + water ? ? Reactants Products expiry: From this lab, I learned that wax burns in a vapor state. Fire requires force b ulge out and group O in grade to burn. The products of a combustion reception are carbon dioxide and water. I also found out that it takes skill to light a match and that its catchy to keep gas where you motivation it to be without a pie-eyed container. There are many an(prenominal) sources of mistake.

The first source of erroneous belief was that if you blow on the candle too hard, the wax vapor blows away and the flame doesnt jump. The next source of error is that if you dont put in the limewater and stopper quickly enough, the carbon dioxide escapes and the water wint turn chalky. A real life practical application for this lab is that if youre cooking and the pan catches on fire, you can just put a cover on the pa! n. The vacuum that you create willing cause the fire to burn itself out when it runs out of oxygen. This lab makes me wonder whether using a bigger flask for the water would cause the water to reach the flame before the oxygen burned out. I wonder if we could percolate the carbon dioxide in a beaker, or if it would escape too fast.If you want to get a full essay, order it on our website: OrderEssay.net
