Yes, burning a candle is a chemical reaction. The easiest way to tell if something is a chemical reaction is if heat or light are given of, a new substance is formed, or a colour change happens. Chemical changes are irreversible.
Yes, whenever a candle burns, it is a combustion reaction between the carbon compounds of the wick and wax of the candle and of oxygen in the air. These compounds burn to create carbon dioxide and water, and also a few smaller carbon compounds, which is evident as the smoke rising occasionally from the flame. The flame you see and the heat you feel rising off of the burning wick is the evidence of an exothermic chemical reaction.

What else can I help you with?
When a candle burns in air which chemical reaction takes place?
combustion
When the candle burns there is a reaction .give the chemical formula of the product in this reaction?
When a candle burns, it undergoes combustion in the presence of oxygen to produce carbon dioxide (CO2) and water (H2O) as the main products. The balanced chemical equation for this combustion reaction is: CxHy + O2 → CO2 + H2O.
Is soot formed as a candle burns a chemical change?
Yes, soot formation when a candle burns is considered a chemical change. This is because the wax molecules in the candle undergo a chemical reaction with oxygen in the air, resulting in the formation of new substances like carbon dioxide, water vapor, and soot particles.
Where does a chemical reaction occur on a candle?
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 physical and chemical changes occur when a wax candle burn?
Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction The rest of the wax melts with the increased temperature. That is the physical change.
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.
Is burning candle getting shorter physical or chemical change?
Burning a candle is a chemical change because the wax undergoes a chemical reaction with oxygen in the air to form new substances like carbon dioxide and water. This process results in the candle getting shorter as it burns.
What energy transfer happens when a candle burns?
When a candle burns, chemical energy stored in the wax is converted into heat energy and light energy through a chemical reaction called combustion. The heat energy causes the wax to melt and then evaporate, while the light energy is emitted as a flame.
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.
When the wick burns and the candle melts is it a chemical or physical change?
it is a chemical change
What form of energy is found in candle ones lighted?
The energy in a lit candle comes from the chemical reaction of the wax with oxygen in the air, producing heat and light through combustion. This chemical energy is converted into thermal (heat) and radiant (light) energy when the candle burns.
What chemicals react when a candle burns?
The candle burn is an oxydation reaction; organic compounds are burned with oxygen.
