Is a compound irreversible?
That depends on what is being mixed together. Two examples of this are: If you mix sand, gravel, and water it is reversible and you can separate the mixture back to its original three parts. If you mix sand, gravel, water, and cement powder it is not reversible as the water will react with the cement powder creating liquid cement and the sand and gravel will form concrete with the liquid cement. After a few hours the liquid cement in the concrete will set and the concrete mixture will become as hard as rock. It is now no longer possible to separate the mixture back to its original four parts.
