A chemist must prepare 750. mL of 1.00 M aqueous silver perchlorate AgCIO 4) working solution. He'll do this by pouring out some 2.96 M aqueous silver perchlorate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the silver perchlorate stock solution that the chemist should pour out.

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 .
