The chemical reaction pathway you've provided involves the transformation of Copper $II$ oxide $CuO$ into Copper $II$ sulfate $CuSO4$, then Copper $II$ hydroxide $Cu(OH)2$, followed by another conversion back to Copper $II$ sulfate $CuSO4$, and finally to elemental Copper $Cu$.

Overall, this pathway involves multiple chemical reactions and transformations of copper ions and molecules before ultimately producing elemental copper.
