Step-by-step explanation:

a)

$k _(sp) = [Ag {}^( + ) ][Cl {}^( - ) ] \\ but \: [Ag {}^( + ) ] = [Cl {}^( - ) ] \\ k _(sp) = [Ag {}^( + ) ] {}^(2) \\ [Ag {}^( + ) ] = \sqrt{k _(sp)} \\ = \sqrt{1.8 * {10}^( - 10) } \\ = 1.34 * {10}^( - 5) mol {dm}^( - 3)$

b)

It has not reached equilibrium because the silver concentration is not yet equal to the value of Ksp.

c)

Yes it will dissolve in order to establish the equilibrium.
