Many important metals occur as sulfide, arsenide, and antimonide minerals, especially in the Sudbury ineral complex. The first step in processing these ores involves "roasting" the ore in air to produce the metal r metal oxide, along with nonmetal oxides that can be serious pollutants if not trapped. Suppose that you roast 2.00 kg of the mineral polymidite, Ni3S4. The balanced equation for the reaction 6: 2 Ni3S4 + 11 0₂ →6 NiO + 8 SO₂ (a) How many kg of NiO can be produced? (b) How many kg of the pollutant SO₂ can be produced? (c) How many liters of air at 25°C are required for roasting? Assume that air contains 23% O₂ by mass, nd that the density of air at 25°C is 1.2 g/L. Molar masses: Ni3S4 304.3 g/mol NiO 74.69 g/mol SO₂ 64.06 g/mol

Looking up one snowy afternoon from a book titled The Moral Case Against Turning Lead Into Gold (Or Vice Versa), your friend Maria (an expert chemist) says this: "Metal sulfides roasted with oxygen produce the corresponding oxide and sulfur dioxide gas." Using Maria'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: %
