Is mixing cement and water reversible?
Portland cement (and the concrete, mortar, thin set, or other masonry product made from it) doesn't dry. Rather, it cures by a chemical reaction initiated by putting water in it. The reaction is irreversible; hence, adding water to cement is an irreversible change.
Is mixing oil and water a reversible or irreversible change?
reversible
Would you that mixing gases is a reversible change?
It isn't easily reversible but, it is reversible. You can use a molecular sieve or a distillation column to separate them.
Is mixing cement and water a irreversible change?
Yes it is. Once mixed it can never be altered or undone
Is mixing cement a chemical or physical change?
Actually both physical and chemical changes are happening during cement mixing.
Is mixing salt and water a reversible or irreversible?
It is reversible. You can allow the water to evaporate, leaving the salt behind.

Mixing sugar and water is reversible or irreversible?
Sugar and Salt
Is mixing flour and water is reversible or irreversible?
no
Mixing sand and sugar is it reversible or irreversible?
Irreversible
Is mixing oil and water a reversible or irreversible change?
reversible
Concrete can be made by mixing water with sand crushed stone and?
A. Cement
Concrete can be made by mixing water with sand crushed stone and what?
cement
What effect has the quantity of mixing water have upon the quality of concrete?
the strength of concrete is effected by water /cement ratio as the water/cement ratio increases the strength of the concrete decreases
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.
Why is mixing of sand with water a reversible change?
Because - you can simply evaporate the water by heating it, and collect the water in a separate vessel - leaving the dry sand intact.
