The lead-acid storage battery is the oldest rechargeable battery in existence. It was invented in 1859 by French physician Gaston Plante and still retains application today, more than 150 years later. There are two reactions that take place during discharge of the lead-acid storage battery. In one step, sulfuric acid decomposes to form sulfur trioxide and water: H₂SO4(1) SO3(g) + H₂O(1) ΔΗ= + 113. kJ In another step, lead, lead(IV) oxide, and sulfur trioxide react to form lead(II) sulfate: Pb(s) + PbO₂(s) + 2SO3(g) → 2 PbSO4(s) Calculate the net change in enthalpy for the formation of one mole of lead (II) sulfate from lead, lead(IV) oxide, and sulfuric acid from these reactions. Round your answer to the nearest kJ. kJ AH = -775. kJ X

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: Fe(s)+CuSO4(aq)→Cu(s)+FeSO4(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 142.mg. Calculate the original concentration of copper(II) sulfate in the sample. Be sure your answer has the correct number of significant digits.

The discharge of chromate ions (CrO42) to sewers or natural waters is of concern because of both its ecological impacts and effects on human health if the receiving water is used as a drinking water source. One way in which chromate can be removed from solution is by its reaction with ferrous iron (Fe²+) to form a mixture of chromic hydroxide and ferric hydroxide solids [Cr(OH)3(s) and Fe(OH)3(s), respectively], which can then be filtered out of the water. The overall reaction can be represented as CrO4 + 3Fe²+ + 8H₂O → Cr(OH)3(s) + Fe(OH)3(s) + 4H+ How much particulate matter would be generated daily by this process at a facility that treats 60 m³/h of a waste stream containing 40 µg/L CrO4²- if the treatment reduced the Cr concentration enough to meet a discharge limit of 10 µg/L (MCL proposed in 2013, voted into law in 2015 and ruled invalid in 2017 for California) or 50 µg/L (current MCL) CrO4²-?
