How would I balance and write a cell schematic representing this reaction as it would occur in a galvanic cell?: SiO3^2- + Mg(s)⟶Si(s) + Mg(OH)2(s)

Any help at all would be appreciated. I am taking an online summer General Chemistry 2 course and I cannot find any examples such as this one within my textbook. I do not usually ask others for assistance but I am genuinely lost with this problem.

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
