What is the equilibrium constant of pure water at 25C?
Tomtit [17]

Answer:

In pure water, at 25C, the [H3O+] and [OH-] ion concentrations are 1.0 x 10-7 M. The value of Kw at 25C is therefore 1.0 x 10-14. Although Kw is defined in terms of the dissociation of water, this equilibrium constant expression is equally valid for solutions of acids and bases dissolved in water.

What do these two changes have in common?
Xelga [282]

Building a tower out of magnetic blocks and water vapor condensing on a bathroom mirror are only physical changes.

A physical change is easily reversible. It does not involve a change in the composition of a substance.

A tower built out of magnetic blocks can easily be pulled apart and water that condensed on a bathroom mirror can easily change back to vapour by heating.

All these are possible because the both processes are only physical changes.
