When the following molecular equation is balanced using the smallest possible integer
coefficients, the values of these coefficients are:
CH4 (g) + CCI4 (g) →→→
CH₂Cl₂ (g)
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 copp
metal precipitates out because of the following chemical reaction:
Fe(s) + CUSO ¿(aq) → Cu(s) + FeSO,(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 500. 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 c
97. mg.
Calculate the original concentration of copper(II) sulfate in the sample. Round your answer to 2 significant digits.
