No. Burning is sometimes a reversible change, as when hydrogen is burned, and it always produces a new compound(s).
Burning wood is an irreversible change because it results in the formation of new substances like ash and smoke that cannot be easily reversed back into wood. The chemical structure of the wood is altered during the burning process, making it impossible to return it to its original form.
Burning a candle is an irreversible change because the wax undergoes a chemical reaction with the oxygen in the air, producing new substances like carbon dioxide, water vapor, and ash. Once the candle has been burned, it cannot be restored to its original state.
Burning of a cracker is an irreversible change. Once the cracker is burnt, it undergoes a chemical reaction that cannot be easily reversed to its original form.
Yes, burning something is a chemical change because it involves a chemical reaction that results in the production of new substances (e.g., ash, smoke, gases). Physical changes, on the other hand, do not alter the chemical composition of a substance.
burning or tree or wood is an irreversible chemical change.
Burning something is irreversible.
Yes, the burning of sugar is a chemical change, as it produces substances with different chemical properties than the reactants.
Burning of an incense stick is a chemical change because it involves a chemical reaction where the compounds in the incense stick are transformed into new substances such as ash, smoke, and gases. This change is irreversible and results in the formation of different chemical compounds than those present in the original incense stick.
Burning wood is an irreversible change because it results in the formation of new substances like ash and smoke that cannot be easily reversed back into wood. The chemical structure of the wood is altered during the burning process, making it impossible to return it to its original form.
Burning is an irreversible change.

Burning a candle is an irreversible change because the wax undergoes a chemical reaction with the oxygen in the air, producing new substances like carbon dioxide, water vapor, and ash. Once the candle has been burned, it cannot be restored to its original state.
Burning of a cracker is an irreversible change. Once the cracker is burnt, it undergoes a chemical reaction that cannot be easily reversed to its original form.
Burning wood in the fireplace is an example of a chemical change because the wood undergoes a chemical reaction to produce heat, light, and ash. This change is irreversible as the wood is transformed into new substances during the process.
Yes, burning something is a chemical change because it involves a chemical reaction that results in the production of new substances (e.g., ash, smoke, gases). Physical changes, on the other hand, do not alter the chemical composition of a substance.
No, burning wax is an irreversible change. When wax is burned, it undergoes a chemical reaction that changes it into different substances (carbon dioxide, water vapor, and heat) that cannot be easily reversed.
Burning a candle involves a chemical change, as the wax is being oxidized by the oxygen in the air to produce heat, light, carbon dioxide, and water vapor. This process is irreversible and results in the formation of new substances, which is characteristic of a chemical change.
