You determine the molecular weight of an enzyme to be 75 kDa. By assaying 5 g of enzyme under saturating [S], you determine the Vmax to be 1.68 moles per second. Calculate the turnover number

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

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 .

Salt in oceans comes from and of rocks
