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.
The burning of the candle (a chemical reaction) is affected by the number of oxygen molecules around it.
So the speed of the chemical reaction is affected by the concentration of oxygen
What else can I help you with?
A melting candle demonstrates which reaction?
A melting candle is an example of a physical change, not a chemical reaction. The process involves a solid candle turning into liquid wax due to the application of heat, with no change in the chemical composition of the wax molecules.
What is the chemical reaction when you burn a candle inside a glass beaker?
It is an oxydation reaction.
How we know a chemical change has occurred when burning a candle?
Burning is a chemical reaction, an oxydation.
What changes the rate of a chemical reaction or allows a chemical reaction to occur?
Heat?
As a candle burns it gets shorter and shorter describe a chemical change that explain this?
I believe there is no chemical equation for this. this is because though the wick burning has a chemical reaction, the wax melting, making the candle shorter, is not undergoing a chemical reaction. simply a short change of state. If you were referring to the wick brurning though, this would be a combustion reaction. hope that helps.

What is the chemical property of a candle?
A candle uses a combustion reaction to release heat and gas.

It is an oxydation reaction.
What comes out of a reaction?
Chemical changes occur after a chemical reaction.

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.
When a candle burns in air which chemical reaction takes place?
combustion

What is energy of a candle?
The energy of a candle comes from the chemical reactions that occur when the candle burns. This process releases heat and light energy in the form of a flame. The energy produced by a candle can be used for lighting or heating purposes.
How does the evolution of gas occur in a chemical reaction give an example?
This is a sign of a chemical reaction.
What provides the chemical potential energy in a candle?
The chemical potential energy in a candle comes from the combustion of the wax through a chemical reaction with oxygen in the air. This reaction releases heat and light energy, which is used as a source of energy for illumination and heating.
