The burning of paper is a chemical change
Step 1 Chemical change:
We can see that the substance undergoes a full chemical reaction into a new compound with a new elemental composition and chemical formula.
As a result of the chemical transformation, the substance's appearance, as well as its chemical composition, are changing. For example, change milk into curd.
Step 2 Explanation: The burning of paper is a chemical change in the substance.
It is because when we burn a piece of paper, it undergoes the combustion reaction, which transforms the substance from a solid to a gaseous state.
As a result, the combustion of paper (Carbon) is regarded a chemical change since the paper transforms into ashes and gas smells emerge.
When burning paper, some gas is released, which turns the white paper into a brownish-black ash color.
