The bond lengths of the X-H bonds in CH4, SiH4, and SnH4 are 1.09, 1.48, and 1.71 Å, respectively. Estimate the length of the Ge-H bond in GeH4. Which of these four hydrides has the weakest X-H bond?Estimated Ge-H bond length = ÅWeakest X-H bond in

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 .
