The Burning Of A Candle

Combustion Reaction: A chemical reaction between a fuel and an oxidizing agent that produces heat.

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

- Results: When liquid wax is exposed to the heat of a match, it transforms back into its original solid state.

Candles are a convenient way of providing light and heat when no electricity is available. They are normally made from paraffin wax with a wick in the middle. Candles can also be made from soy wax or other plant wax, animal fat or bee wax. Wax acts as a fuel to keep the candle burning. The wick has to be an absorbent twine with

In a combustion reaction, a compound or element reacts with oxygen, releasing a large amount of energy in the form of light and heat.

| Combustion product reacted by becoming cold, dissolving, and no gas formation with an end product is clear colorless solution.

1. Place a small amount of wax from a birthday candle into a test tube. Heat gently over a burner flame until the wax melts completely; then allow

The luminous yellow flame is smoky because no air is entering the burner and hydrocarbon is converted into carbon dioxide

Station two: Station two shows that when a beaker full of cold water is placed over a hot candle flame, many observations take place signifying a chemical reaction, as well as a

This article focuses on the Revolutionary period of Colonial Williamsburg when candles were a primary light source in homes. At this time in history there were four primary substances used in making candles, spermaceti, tallow, beeswax, and myrtle or bayberry wax. The three latter substances were produced in Virginia. Methods of making these candles and how they were shaped are described in the article.

Combustion vs Respiration Activity 1 - Answer the following question in relation to combustion Explain what a combustion reaction is. Combustion usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water. Write the general word equation for combustion. In words, the equation for combustion, in most cases, is a hydrocarbon plus oxygen equals carbon dioxide plus water plus heat.

It was desired to compare a theoretical value of enthalpy of combustion to a literature value. To do this, the theoretical value was calculated using a literature value for the heat of sublimation of naphthalene, the heat of vaporization of water and average bond energies, given in Table 1 of the lab packet.1 Equations (1) and (5) were used to calculate the theoretical enthalpy of combustion of gaseous naphthalene, where n was the number of moles, m was the number of bonds, and ΔH was the average bond energy:

In this project we examined three explanations that talk about (a) candle(s) in a jar and their investigation reasoning to why the labs they did were concluding in such a way. The first explanation resulted that the candle inside the jar took up all the oxygen molecules inside the flask which then lowers the pressure inside and the higher pressure outside the flask is what causes the water to rise up. The second explanation resulted in that the air pressure increases inside the jar because of the heat from the candle, which causes air to come out of the jar and once the candle cools down the pressure decreases and the pressure outside the jar increases which results in pushing the air in and making the water rise up. The third explanation resulted in oxygen inside the flask becoming carbon dioxide which then dissolves in water causing the air pressure to decrease under the glass and the higher pressure outside the flask pushed the water up the flask. I believe that explanation number three is right because the flame causes carbon dioxide to be created and that

I chose the topic do white candles burn faster than colored ones because whenever my mom burns candles, the white candles sometimes tend to burn faster than the colored ones. So for this year’s science project, my essential question is ‘Do white candles burn longer than colored ones?’ I’m going to conduct this experiment twice to test accuracy and just in case, if possible, if I made any mistakes.

At one time, scented candles were a rare luxury to be enjoyed only by the rich while the rest of us made do with the ordinary white candles during power cuts and at Christmas time. However, that has all changed, and an endless variety of fragrances are filling our homes and relaxing us. Candles are just one of these sources of wonderful smells, but they are also a very popular source, partially because of the number of different forms in which they are available but also because they look so good with their burning flame.
