Suppose a student started with 142.0 mg of trans-cinnamic acid, 412 mg of pyridinium tribromide, and 2.30 mL of glacial acetic acid. After the reaction and workup, the student ended up with 0.2223 g of brominated product. Calculate the student\'s theoretical and percent yields.

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 .

The molar mass of cu is 63.55 g/mol. the number of grams of cu produced in this reaction is

How many grams of cupric sulfate pentahydrate are needed to prepare 50.00 ml of 0.0800m cuso4× 5h2o?
