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!
Is the smoke from burning wood a chemical change?
No. You must not confuse the PROCESS of converting some chemical products to others, with the RESULT. The PROCESS of converting wood and oxygen to smoke is a chemical change. The SMOKE itself is not.
What is a sign that a chemical change has occurred smoke broken pieces change in shape or change in state?
The production of smoke from something burning would be a sign of a chemical change. Broken pieces, change in shape, or change in state are all physical changes.
Is heating a wood splint a chemical or physical change?
Heating a wood splint is a chemical change. If this was done in something like a test tube, you will see many things occur that indicate this. First, you will see a werid kind of smoke, the splint turning into black stuff, and a really bad smell. Well the smoke is CO2 and the black stuff is ash from the burning. Because there is a new substance being made and the identity of the original substance(your splint) has changed, the reaction is chemical.

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?
Candle wax burning is a chemical change. During the process of burning, the wax undergoes a chemical reaction with oxygen from the air, resulting in the formation of new substances and the release of energy in the form of heat and light. This to due to the fact that candle waxes is a hydrocarbon compound , namely, it is the paraffin wax. Therefore, to be more specific, the combustion equation can be written as follows: Paraffin Wax (C25H52) + Oxygen (O2) → Carbon Dioxide (CO2) + Water Vapor (H2O) If you wish to learn more about candles, please check out ohcans candles.

It is chemica changel because it produces gas and the smoke it produce is one of the evidence that it is really a chemical change, also you can't put it back to its beginning state.
Is a candle burns chemical reaction?
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.Yes, burning a candle is a chemical reaction.
