Is the burning of wax, chemical change?

It's a combustion reaction. Next time ask yourself the question, is this reversible? If you melt ice, you can easily turn it back into ice by removing heat. It's a physical change. When you burn wax it turns into CO2 and water vapor. read more

Yes,buring of wax is a chemical change. When a candle is burning two things occur simultaneously. First, melting of wax and second, burning of wax. In these the melting of wax is a physical change but the burning of wax is a chemical change. Because in burning oxidation of wax actually takes place which is a chemical change. read more

A burning candle is an example of a chemical change because the paraffin wax, which is a hydrocarbon, undergoes a chemical reaction with oxygen to form water and carbon dioxide gas. Because the chemical structure of the paraffin has been altered, this is a chemical change. read more

Burning of candle is both physical and chemical change. Burning of candle melts the wax and hence physical state of wax has changed from solid to liquid. Again the wax combines with the atmosphere oxygen and changes to carbon dioxide, heat and light. read more
