Yes, it is chemical: look at the remainings of the wick: black carbon-like, not white fiber anymore.

Is a burning candle a reversible or non reversible change?
Non reversible, after the wick has been burned, it is impossible to reverse the effects of the change.
Why burning of candle is a physical and chemical change?
CHEMICAL
What is the physical and chemical change that occurs when a birthday candle is lit on a cake?
There are multiple physical changes and chemical changes that occur when a candle burns. One physical change is that the candle melts back into liquid wax. One chemical change is flame burning on the wick.
Why burning candle is chemical change?
It is a chemical change because the burning thread is combusted. The combustion is an oxidation reaction. Most importantly, it is a chemical change because after burning, the chemical properties of the thread is changed entirely!
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.
Is the wick of a burning candle part of the chemical reaction?
Yes, the wick is also burned.
When the wick burns and the candle melts is it a chemical or physical change?
it is a chemical change
Is lighting a chemical change?
Yes. While act of melting wax is a physical change, because you can remould it, the wax is actually what is primarily burned as fuel. You cannot unburn the wick nor the consumed wax. Remember, if it can be redone, it is probably physical and vice versa.The wick of a candle is used to light it and is used as a medium for burning the wax. As the wax is heated, it is soaked into the burning wick. As the fire burns the wax on the wick, more melted wax is absorbed into by the wick. As the wax burns down, so does the wick.
What type of reaction occurs when a candle is burned?
There are 2; the melting of the candles wax is physical but the wick burning is chemical.
Is a burning candle a reversible or non reversible change?
Non reversible, after the wick has been burned, it is impossible to reverse the effects of the change.
When a candle burns both physical and chemical changes take place Identify these changes?
the physical change is -the shape of the candle changes,some of the wax becomes liquid to solid. chemical change-the wick is burned *Hi just wanted to say that this person above is wrong...I mean, the wick burning would be a chemical change because it is combustion. They are wrong because the wick doesn't actually burn.The wax is absorbed by the wick which cools it off. Eventually the wick becomes too long and the top of it dries out and falls off into the wax. Fact being, the wax vapor burns. You should do some more individual research for details because there is more. Thanks!

CHEMICAL
Is a candle burning a physical change?
It is actually both. The burning of the wick involves a chemical change. The physical change is the wax.
Is candle burning physical change?
Physical change means change physically while chemical change means change chemically or change in chemical properties.Like if you would drop a chip of zinc in sulphuric acid it will its color will be changed which is no doubt a physical change.But,also its properties are changed as it will be transformed into zinc sulphate from simple zinc,thus it also undergoes a chemical change. Now,with your question,the candle breaks but the candle remains the candle,so,its not a chemical change but a physical change only.Hope it helps!
What part of a burning candle takes place and physical change?
The melting of the wax is a physical change. The burning the of wick is the chemical change

Why is melting of covered candle a physical change while burning of a candle wick a chemical change?
This is because a candle will change its whole form and stay that way, which is a physical outer change. And a candle wick only burns, it doesn't change it's appearance.
