Many computer chips are manufactured from silicon, which occurs in nature as sio2 . when sio2 is heated to melting, it reacts with solid carbon to form liquid silicon and carbon monoxide gas. in an industrial preparation of silicon, 155.3kg of sio2 of is allowed to react with 79.3kg of carbon to produce 66.2kg of silicon. what is the theoretical yield for the reaction in kg si? what is the percent yield for the reaction?

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 .
