reversable
Iron sulfide is a chemical compound. A process or reaction may be reversible or irreversible; a compound isn't.
It's irreversible
No, burning a candle is not reversible. When a candle is burned, the wax is melted and the wick is consumed, resulting in irreversible changes to the candle's structure.
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.
The melting of a candle is a reversible change because the solid wax can be cooled and solidified again to form a new candle.
irreversible change.
areversible action produces new material
Yes, candle burning is a reversible change because it can be undone by extinguishing the flame. When the flame is removed, the wax solidifies again, demonstrating that the process of burning is reversible by cooling down the wax.
Physical changes can be reversible or irreversible depending on the nature of the change. For example, melting ice is reversible as it can be frozen again, while cutting a piece of paper into smaller pieces is irreversible.
An irreversible change is a process that cannot be undone or reversed. Once the change occurs, it is permanent and cannot be restored to its original state. An example of an irreversible change is burning a piece of paper: once the paper is burnt, it cannot be turned back into its original form.
