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: Fe(s) + CuSO 4(aq) Cu(s) + FESO 4(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 350. mL 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 146. mg. Calculate the…
The decomposition of nitroglycerin (C3H3N;O,), a powerful explosive, may be represented by the reaction: C;HŞN3O9 – N2 + CO2 + H20 + O2 1.
