Heavy metal sulfides like CdS and PbS are often significant components of mine tailings (the piles of waste and low-grade ores discarded by a mining operation). While these sulfides are quite insoluble in water (Ksp of CdS = 1 E -27, Ksp of PbS = 3 E -28), over the years rainwater and snowmelt can slowly dissolve small amounts of these heavy metals, washing them into streams and other natural waters. If these mine tailings are located in an area that is impacted by acid rain, would you expect heavy metal dissolution into natural waters to increase or decrease? Use chemical reactions to justify your answer.

Lead poisoning is a serious condition resulting from the ingestion of lead in food, water, or other environmental sources. It affects the central nervous system, leading to a variety of symptoms such as distractibility, lethargy, and loss of motor coordination. Lead poisoning is treated with chelating agents, substances that bind to metal ions, allowing it to be eliminated in the urine. A modern chelating agent used for this purpose is succimer (C4H6O4S2). Suppose you are trying to determine the appropriate dose for succimer treatment of lead poisoning. What minimum mass of succimer (in mgmg) is needed to bind all of the lead in a patient's bloodstream? Assume that patient blood lead levels are 37 μg/dL, that total blood volume is 5.0 L, and that one mole of succimer binds one mole of lead.
Write the chemical equation for the word equation below. Each blank should be a different substance and the reaction does not need to be balanced. Molybdenum(IV) chromate reacts with lithium telluride to make molybdenum(IV) telluride and lithium chromate
Looking up one snowy afternoon from a book titled The Moral Case Against Turning Lead Into Gold (Or Vice Versa), your friend Hans (an expert chemist) says this: "Many metals can be produced from their oxide ores by reaction at high temperatures with carbon monoxide. Carbon dioxide is a byproduct." Using Hans's statement, and what you already know about chemistry, predict the products of the following reaction. Be sure your chemical equation is balanced!

In acidic solution, sodium oxalate, Na₂C₂O4, is oxidized to CO₂ by MnO4. In the process, MnO, is reduced to Mn² +. To titrate a 0.855 g sample of Na₂C₂O₁, 43.7 mL of an MnO solution were required. The same MnO solution is then used to analyze samples that contain uranium. A 12.8 g sample of a material that contains uranium required 29.3 mL of the MnO, solution for titration. During titration, the uranium sample was oxidized as shown. UO² (aq) → UO *(aq) Calculate the mass percent of uranium in the sample. mass percent of uranium: %
