When a candle burns wax undergoes a combustion reaction would a candle burn longer in the open or when covered with an inverted glass jar?
The candle burning in the open will burn longer, because it has easy access to oxygen to sustain the reaction. The flame of the candle burning under the jar will go out quickly, since it will use up its available oxygen faster than the oxygen can be replenished. Even if the jar is open at the bottom, the heat, carbon monoxide, and carbon dioxide produced by the flame will prevent sufficient oxygen from getting to the flame to feed it.
What is the chemical reaction when you burn a candle?
When a candle burns the reactions that occur are both chemical and physical. Chemical reaction is when substances are mixed together to create a different material. A physical reaction is when there is a change in the appearance of the substance. For example when water turns to ice, and when chocolate melts. The chemical reaction that happens when a candle burns is when the oxygen combines with the paraffin. When this happens, this makes carbon dioxide, water and other materials. When the wax reacts with the oxygen it gives off light and heat. The more oxygen that reacts with the candle when it burns, the brighter and hotter it is. The physical reaction that occurs is when the candle wax melts. When the energy (light and heat) inside of the candle is released it helps to melt the candle.
Does a soy candle burn as long as a beeswax candle?
Beeswax is known to be a long burning wax. Even so, it burns the same amount of time as a candle made from soy. The length of time a candle burns depends upon how tight the wax was wrapped during production. The tighter the wrap, the longer the burn.
Burning candle what is actually burning?
Vapours of the candle wax, which contain carbon and hydrogen, react with oxygen in the air to create carbon dioxide and water. Often, the combustion is incomplete and small amounts of carbon monoxide as well as carbon (soot) are released.
Will a candle burn longer in a large jar then a small jar?
In a large jar as there should be more oxygen.
Why do you think that candle with plant would burn for a longer time?
Candle burns oxygen. Plant produces oxygen from Carbon Dioxide. plant produces oxygen, which is burned by candle. Candle lasts longer because more oxygen is present
What does the wax of a candle react with when it burns?
Oxygen.
Is the reason a colored candle burns longer because of the dyes in the darker candle?
no
How does oxygen Affect how fast a candle will burn?
when a candle burns, the wax is reacting with oxygen in the air to give out heat and light. If you give the candle more oxygen then it will burn brighter, but it will burn out more quickly. It all depends whether the candle has a high or low concentration of oxygen. The main reason why the candle burns brighter is because there is a better chance that the oxygen will bump into the wax on the wick. when a candle burns, the wax is reacting with oxygen in the air to give out heat and light.

Why does the candle extends?
because it burns the oxygen and turns it to co2
What chemicals react when a candle burns?
The candle burn is an oxydation reaction; organic compounds are burned with oxygen.
Why does a candle go out when a jar is put over?
The candle consumes all the oxygen in the confined space and burns out
When a candle burns what compounds are combine with oxygen?
Carbon is combined with oxygen forming carbon dioxide.
Why would a candle use too much air?
It burns the oxygen. r

Why do candles need oxygen?
YES. The available amount of oxygen in air regulates the candles burn. The oxygen burns with the paraffin wax. Both are consumed. A mix of more oxygen will burn faster and hotter. Rapid oxydation is dangerous.
Which is to burn longer a tallow candle or a wax candle?
If you freeze the candle, before using it, it will burn for a longer period of time. ANSWER Beeswax burns very quickly.
