Does a candle with flame have cells?
Not really. The candle would have molecules, but the flame falls under energy and would break down to quanta.
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.

How do you make a roaring flame on the Bunsen burner?
To get a roaring (blue) flame you simply turn the sleeve on the Bunsen burner's chimney to completely open the air hole under it. The new blue flame will be hard to see so close the air hole afterwards to make a visible flame.
Will candle produce nitrogen when it's burning?
Will candle produce nitrogen when it's burning? The only substances produced are carbon dioxide, carbon monoxide and water. Under perfect circumstances. So called efficient burning.

Why does a flame not get extinguished when a wire gauze was placed on top of it in a candle observation chemistry lab?
A flame is not extinguished when a wire gauze is placed on top of it because the flame is still exposed to oxygen. The gauze has holes, through which oxygen can flow. Additionally, oxygen can reach the flame from under the gauze. Consequently, the flame is not extinguished.

The candle under the beaker gave out after about thirty seconds How would you expect this to be different in different sizes of beakers?
The higher the volume, the more the flame will last.
Why do candles go out when we put glass jars over them?
The concentration of oxygen in the air in the beaker becomes insufficient for the flame to carry on burning, or the carbon dioxide produced is trapped in the beaker, and the increased concentration causes the flame to be extinguished.
Can you hold a balloon under a flame without popping it?
UNDER a flame? Sure, why not? Over a flame? Close? Uhhh... NO
How can you tell that the burning of a candle causes both physical and chemical change?
By observation: 1. A flame shows that heat is being generated, indicating a chemical change taking place. 2. A physical change would be the solid wax changing to liquid under the flame.
Can there be fire in tunnels under the earth?
Yes. Fire requires only three things: oxygen, fuel, and something to start the blaze (a match or candle flame, lightning strike, spark, etc.).
What to do if father did voodoo on you to pick skin and what procedures were used?

What is the temperature of a candle flame?
== The temperature of a candle flame is about 800 degrees Celsius. == Depending on the wax, and the concentrations of water of oxygen in the air, somewhere between 1,200 degrees and 1,700 degrees Celsius.The heat capacity and conductivity of air and the exhaust products of combustion, however, are both very low. In practice, candle flames do not seem very hot (much like metal feels colder than wood at room temperature, though they are the same temperature).The outer core of the candle flame is light blue -- 1670 K (1400 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange and finally red. The further you reach to the center of the flame, the lower the temperature will be. The red portion is around 1070 K (800 °C). The reason there is this variation in a candle's flame color is because air convection pulls the warmer gasses upwards.
