During the burning of a candle, the wax (hydrocarbons) undergoes a combustion reaction with oxygen from the air. This reaction produces carbon dioxide, water vapor, heat, and light. The heat melts and vaporizes the wax, while the light comes from the glowing soot particles that are formed during incomplete combustion.

What are the steps to prove that a burning of a candle is physical as well as a chemical change?
To prove that the burning of a candle is a physical and chemical change, you can observe the physical changes such as the melting of the wax and the formation of soot. Additionally, you can analyze the chemical changes by noting the production of carbon dioxide and water vapor during the combustion process. By observing both physical and chemical changes, you can demonstrate that burning a candle involves both types of transformations.
Is candle wax burning a physical change?
For the wax, yes. It changes to a liquid and then back to a solid. But some of the wax is also consumed in a chemical change as it oxidizes, along with the burning wick.
Why is burning a candle chemical change?
Phenomena during the candle burning:- melting- evaporation- oxydation- thermal decompositionIt is a chemical change because gas is use as a chemical. It also has friction when your trying to light it. The match is similar.Burning a candle is a chemical change because the wick is being changed into two things: ash and smoke. It is no longer a wick, and it's properties have changed.because oxygen is reacting with the flame...
Is burning a candle wick a chemical change?
It is a chemical change because you can't put it back together exactly the way it was before. Yes, a chemical change is taking place. Even simple cooking produces chemical changes. The smoke and the temperature change are good signs a chemical change is taking place
Why burning of incense stick is a chemical change?
Burning of an incense stick is a chemical change because it involves the combustion of the organic compounds present in the incense, leading to the formation of new chemical substances such as ash, water vapor, and carbon dioxide. The molecular composition of the incense stick changes irreversibly during burning, making it a chemical reaction.
What does candle wax react with?
Candle wax typically reacts with oxygen in the air when it is burning, producing heat, light, and carbon dioxide. The chemical reaction that occurs during the burning of candle wax is called combustion.

Is a candle burning chemical change?
Yes, burning a candle is a chemical change. New chemical compounds are being formed as the reaction continues. The paraffin in the candle is a hydrocarbon chain, and it is "breaking down" chemically using oxygen from the air to form (idealy) carbon dioxide and water. But there are also physical changes that take place at the same time. Phenomena during the candle burning: - melting (physical phenomenon) - evaporation (may be considered a chemical but also a physical phenomenon) - oxydation - reaction with oxygen, burning (chemical phenomenon) - thermal decomposition (chemical phenomenon)
What name is given to a process such as burning a candle?
The process of burning a candle is called combustion, which is a chemical reaction involving oxygen that produces heat and light. During combustion, the wax in the candle combines with oxygen in the air to release carbon dioxide and water vapor along with heat and light.

Is it a physical change when a candle changes size by burning?
Oh, dude, yes, it's totally a physical change when a candle burns and changes size. The wax is melting and then solidifying again as it cools down, so it's like a hot and cold dance party for the molecules. It's not like the candle magically grows or shrinks, it's just physics doing its thing.
Mass does not change during a chemical change how about for a physical change?
Physical changes are like cutting paper. The mass does not change. Chemical changes do not change total mass either. If you put a candle in a sealed container so that you may measure the total mass of the candle and the air before burning, then light the candle electrically but keep everything sealed, the total mass after burning will still be the same. But if you measure only the candle, then its mass has changed. So the mass of one single 'ingredient' will change during a chemical change.
Is burning a candle wick a chemical change?

How could you check that mass of the candle change during burning?
Put the candle on a technical balance.
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.
