Ksp, the product of solubility constant is given by the product of the concentrations in the equilibrium of the species on the right hand of the equillibrium reaction, each raised to a power that is its coeffiicient in the equillibrium reaction.

So you must start by writing the equilibrium reaction:

Fe(OH)3 (s) ----> Fe(3+) aq  +   3 (OH-) aq

Now you can state the formula for the Ksp

=> Ksp = [Fe (3+) aq] [OH-]^3

So, the answer is the third option of the list.

14. Which group of diamagnetic transition metals exhibits trends in density and melting points that don't match the same trends
inn [45]

Answer:

Group 12

Explanation:

Group 12 transition metals are diamagnetic. They behave properties that distinguish them. They naturally have twelve electrons hence their outermost shell is fully filled.

Transition metals have high densities which increases down the group. However, the increase in density of transition elements of group 12 varies with temperature at a rate that is quite different from other transition elements. Hence the differences in the value of melting points and density changes by only a very small amount as you come down group 12 compared to other groups of transition elements.
