Candle Combustion Experiment

The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel, which leaves a clean test tube. Incomplete combustion is the reaction of an element or compound with oxygen to produce some oxides with less oxygen than the most common oxides. Incomplete combustion occurs when there is not enough oxygen to react

What Is The Unknown White Compound By Alexander Medina Lab Partners Maxwell Yurs, Eugene Floersch, Mesih Harri Abstract A white compound is found, but its identity is unknown.

Latent heat of vaporization The heat that is absorbed when one gram of liquid is transformed into vapor at the boiling point under one atmosphere of pressure and the result is expressed in BTUs per pound or calories per gram.

Wind has been around since the beginning of time with the ability to move air. Air contains roughly twenty percent oxygen, and this oxygen is what the entire human race lives on to breathe and function. Oxygen, also, is very reactive and is involved in many chemical reactions here on Earth. One of oxygen’s key relationships is its one with fire. Fire has given humans a light source for thousands of years and plays a great role in the development of their species. A popular way in which fire is manifested is through the use of candles. The fire on a candle is affected by wind, but how does wind speed affect a candle flame?

The purpose of this lab was to observe the characteristic colors of metallic ions using a flame test.

The purpose of this lab is to evaluate how surface area affects the speed at which paper combusts. Once completed, it will be known if a folded paper with, a small surface area, burns faster or slower than an unfolded paper. In addition to this the lab will demonstrate how expanding the paper's surface area (done by ripping it into pieces and crumpling) affects the speed of combustion.

A feeling that I’ve had lately is sympathy because there are many persons in school that I literally didn’t knew about and now knowing more about them, their lives, their past, their family, their culture, their goals, their passions and other personal things made me realize how many things we have in common and how I can relate with each person. The metaphor I created to express this feeling is that I always feel like a candle melting myself but always keeping the fire on, letting the smoke go away. I think this metaphor is justified that I put myself as an example of a candle because I am patient, I will always be there for you and even if I stay away of you...I will always remember the things we shared with each

I like that you got creative with the props you chose. I don't know if I would have used a candle just because it is a fire hazard and candle wax can get everywhere i'm also thinking you used a candle stick. I do love the analogy you created about protecting her self-esteem but I believe it would be more effective if she had put a physical shield around the candle. When you have low self-esteem not only do you have to build it up, but you have to learn to toughen up a bit and build a thick skin to keep from being so fragile. I am not sure if the candle really drives that home for me, but then again I am picturing a tall candlestick maybe it were a candle in a

I believe that we should continue to go through with the new product lines. After looking at a cost breakdown, the imprinted candles are a clear choice to make an immediate impact on our profit margins. We have enough room to have our desired markup on the cost per unit, and we still will be below the selling price of the candle.

When all the gases were tested with the indicator solution, the carbon dioxide was the only gas that had appeared to become acidic. This was known because the solution had turned from blue to yellow. The final test consisted of blowing all the gases onto the remaining embers from a lit wood splint. The carbon dioxide blew out the embers while the oxygen made the embers glow brighter. The exhaled air and dry air did not seem to have any major effect on the embers.

Unknown #1 is lithium nitrate, because it had the same physical appearance and same flame color as

Is our perception ruled by our cultural heritage? Can we really separate our scientific mind from our spirituality? Gaston Bachelard brings an important topic to us through his book The Flame of a Candle. The author goes beyond the physical phenomenon and uses It as a metaphor to explain the human nature and its morality. The human psyche is seen through the lenses of light, vivid like fire. The flame of the candle purifies itself like our human nature which has evil inside but through spirituality is been purify and brings light to our dark side. This could be considered an specific point of view but I think today we would see this as human opposites nature, our two sides that are in continuous interaction and change. On the other hand, from a physical standpoint of view the flame is keeping us awake, is allowing us to see, is connecting us to our subconscious and our imagination. Like the inner eye, explore in previous readings, imagination is the key to sight and experience. I think the author and its philosophy reinforces the idea of light as knowledge and the flame bright,
