###### FREE Expert Solution

We’re being asked to determine the Q when 2.00 x 10-3 M Ca2+ and  3.00 x 10-2 M SO2- are mixed.

The reaction quotient expression is:

$\overline{){\mathbf{Q}}{\mathbf{=}}\frac{\mathbf{products}}{\overline{)\mathbf{reactants}}}{\mathbf{=}}\mathbf{\left[}{\mathbf{Ca}}^{\mathbf{2}\mathbf{+}}\mathbf{\right]}\mathbf{\left[}{{\mathbf{SO}}_{\mathbf{4}}}^{\mathbf{2}\mathbf{-}}\mathbf{\right]}}$
