Yes it is a chemical change because when you burn paper it cannot be reversed. If it had been a physical change then you would have been able to reverse what you have done to the paper, by turning it back to its original state.
Burning is an oxydation reaction.
Burning is a sign of a chemical change
Burning paper.
the paper undergoes combustion, a type of chemical reaction
combustion
1. Burning of paper 2. Vulcanizing of paper
A chemical reaction, and also a reaction in general.
Yes, burning a paper clip is a chemical change because it involves a chemical reaction where the paper clip combines with oxygen to produce new substances like ash and possibly some metal oxides.
An example of oxidation would be paper burning because it involves a chemical reaction where paper combines with oxygen in the air to produce heat and light. Water evaporating and sugar melting are physical changes, not chemical reactions involving oxidation.
Burning wood is a chemical reaction because combustion (burning) is an oxidation reaction.
Burning of wood and paper is a chemical change because it involves a chemical reaction where the substances are transformed into new substances (ashes, carbon dioxide, etc.) with different properties than the original materials.
Burning is a chemical reaction (oxidation).
