Write the balanced chemical equation that occurs if Hg(s), HgCl2(aq), Mn(s), and MnCl2(aq) are mixed together?

I do not know of any reaction that would occur if these 4 substances were added together to a container of water .
But , If you add manganese metal to a solution of mercury (11) chloride, a single displacement reaction will occur to produce mercury metal and manganese(11) chloride.
This reaction is shown in the following equation:
Mn(s) + HgCl2(aq) → Hg(s) + MnCl2(aq)

Mn(s) + HgCl₂(aq) → MnCl₂(aq) + Hg(l)
