[Maximum number: 1]

Questions 27-29 refer to the following equation.

\mathrm{Tl}^{+}(a q)+\mathrm{Cl}^{-}(a q) \rightarrow \operatorname{TlCl}(s)

A chemist mixes a dilute solution of thallium perchlorate with a dilute solution of potassium chloride to precipitate thallium chloride $\left(K_{s p}=1.9 \times\right.$ $10^{-4}$ ).

If equal volumes of 2.0 millimolar solutions are mixed, which of the following particulate views represents the experiment after the reactants are mixed thoroughly and solids are given time to precipitate?
