How do I write the cell schematic for SiO3^2-(aq) + Mg(s) —> Si(s) + Mg(OH)2(s)?

I have made a genuine attempt at trying to solve this problem but I can’t quite get it. I have been able to solve other cell schematic problems up until this point. I could not find any examples like this one in my textbook. I am also taking General Chemistry 2 online so help is limited, so any help at all is appreciated!

First step would be to determine both redox couples involved.

Note that the reaction is not balanced and the equation doesn't list all reactants involved.

Yes, I managed to balance the reaction and ended up with    2Mg + 3H2O + SiO3^2- —> 2Mg(OH)2 + Si + 2OH^-

I’m confused about how I would write the cell schematic if there is solid mg on both sides.
