8.7M  Is the solubility of Ca(oh)2  in water at a given Ksp of 6.5 .10-6  and molar mass of   74.09g/mol.

Solubility is defined as the amount of the substance  dissolved in a given amount of solvent at a certain temperature.

Ca(OH)2   à  Ca2+  +  2OH-

Ksp = 6.5 .10-6

Molar mass= 74.09 g/mol

Ksp is solubility product constant which describes the equilibrium between a solid and its ion in solution.

          Ksp=[Ca2+] [OH2-]

      6.5 .10-6 = S. (74.09g/mol +S)

      6.5 .10-6 = S .( 74.09M)

        S = 6.5 .10-6 /74.09 M

            =  8.7 M

       So, the solubility of Ca(OH)2  is  8.7M.

Novosadov [1.4K]

B. Mn + NiBr₂  →  Ni + MnBr₂

Explanation:

The reaction that can be predicted of all is Mn + NiBr₂  →  Ni + MnBr₂.

The activity series is used to predict the products of single displacement reactions.

The series ranks metals in order of their reactivity. Those higher up in the series are highly reactive metals. Those at the bottom are slightly to non-reactive metals.

For a single displacement reaction to occur, a metal higher up in the activity series displaces one that is lower in the series.

  Reaction A will not occur, Ba is higher in the series

  Reaction C will not occur, Pt and Au are unreactive

  Reaction D will not occur as Zn is lower in the series

Mn is higher in the reactivity series and it will displace Ni from the solution.
