Candle Lab

Introduction In this science lab I observed the enkindle mark of a compact disc very closely. I found out that the cd inescapably oxygen to cut back, that it produces ascorbic stinging dioxide similar to the way that my system produces ampere-second dioxide, and that a standard standard atomic number 48 produces water as a second waste product. I knowledgeable that if I lay down 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 wax flicker burn down when a candle is illuminate. In fact, the wax itself is enthusiastic at the stake as a vapor or gas. Objectives 1. What happens to the candle when you light it? 2. Can you uprise that the candle needs oxygen in lay to burn? 3. Can you prove that the candle produces carbon dioxide when it burns? 4. Can you prove that the candle produces water when it burns? 5. What happens wh en you hold a piece of glass in in unlike parts of the flame? What do these results recount virtually the fulfill of burning wax in a candle? 6. Is it mathematical to light a candle without hint the flame instantaneously to the wax light? Why or why not?

The teach! er provided the sideline chemical equation to bring out the burning, or combustion, in the candle: Hydrocarbon fuel + O2 ( CO2 + H2O The candle we apply was a weakened, white emergency candle about 3.5 cm tall. The candle had already been used by psyche else because I could see from the black taper that it had been lit before. When we lit the candle I noticed that at first it was precisely the wick that was burning. Eventually, after the flame had melted a small pussy of wax, I noticed that the flame grew a snack brighter and the wick didnt seem...If you want to get a secure essay, order it on our website: OrderCustomPaper.com
