Answer:

A is  Mg^2+

B is K^+

C is Se^2-

D is Cl^-

Ca^2+ lies between  Mg^2+ and K^+

S^2-  lies between K^+ and Se^2-

Explanation:

I have attached an image of the four spheres.

Remember that, cations are smaller in size than the corresponding atom atom because the formation of a cation often involves the removal of an entire shell. Anions are larger in size than the corresponding atom because an electron is added thereby expanding the electron cloud and size of the anion.

From left to right let us designate the spheres as ABCD.

A is  Mg^2+

B is K^+

C is Se^2-

D is Cl^-

Ca^2+ lies between  Mg^2+ and K^+

S^2-  lies between K^+ and Se^2-

Liquid water and water vapor reach equilibrium only in a closed container. Why?
Sunny_sXe [5.5K]
Because water vapor, uncontained, will diffuse out into the atmosphere and is not close enough to condense back into the liquid water, so no equilib. can be established.
