There are two steps in the extraction of copper metal from chalcocite, a copper ore. In the first step, copper(1) sulfide and oxygen react to form copper(1) oxide and sulfur dioxide: 2 Cu,S(3) + 30,(g) 2 Cu,O(s) + 2 SO,(8) In the second step, copper(1) oxide and carbon react to form copper and carbon monoxide: CusO(s) + C(s) 2 Cu(s) + CO(g) Suppose the yield of the first step is 86.% and the yield of the second step is 67.%. Calculate the mass of oxygen required to make 10,0 kg of copper. Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits.

The compound sodium thiosulfate pentahydrate, Na2S2 O3-5H2O, is important commercially to the photography business as "hypo," because it has the ability to dissolve unreacted silver salts from photographic film during development. Sodium thiosulfate pentahydrate can be produced by boiling elemental sulfur in an aqueous solution of sodium sulfite. S8 (s) + Na2 SO3 (aq) + H2O(1) → Na2 S2 O3-5H2 O(s) (unbalanced) What is the theoretical yield of sodium thiosulfate pentahydrate when 3.25 g of sulfur is boiled with 13.1 g of sodium sulfite? Sodium thiosulfate pentahydrate is very soluble in water. What is the percent yield of the synthesis if a student doing this experiment is able to isolate (collect) only 5.26 g of the product?
Standard airbags for automobiles used to implement the formation of sodium azide as a source of nitrogen gas. This has since been replaced due to the potential caustic nature of the products. The sodium azide required for automobile air bags is made by the reaction of sodium metal with dinitrogen oxide in liquid ammonia: 3N2O(g) + 4Na(s) + NH3(l)→ NaN3(s) + 3NaOH(s) + 2N2(g) a. You have 65.0 g of sodium and a 35.0 L flask containing N2O gas with a pressure of 2.12 atm at 296 K. What is the maximum possible yield (in grams) of the NaN3?

15. Kkura found a sulfide ore in the dungeon which she identified to be chalcocite. While waiting for her debut, she read from a journal that grinding and "roasting" (heated strongly with oxygen gas) chalcocite can generate copper (1) oxide, a pigment used to color ceramics. Find the amount of copper(I) oxide she can produce from 53 grams copper(I) sulfide. Cu2S(s) + O2(g) –> Cu2O(s) + SO2(g)

2+ Natural waters often contain relatively high levels of calcium ion, Ca²+, and hydrogen carbonate ion (bicarbonate), HCO3¯, from the leaching of minerals into the water. When such water is used commercially or in the home, heating of the water leads to the formation of solid calcium carbonate, CaCO3, which forms a deposit ("scale") on the interior of boilers, pipes, and other plumbing fixtures. Ca(HCO3)2 (aq) → CaCO3 (s) + CO2(g) + H₂O(1) If a sample of well water contains 0.0016 mg of Ca(HCO3)2 per milliliter, what mass of CaCO3 scale would 1.0 mL of this water be capable of depositing?

The manufacture of nitrogen trifluoride is a growing industry, due to its use as a plasma etchant in the semiconductor industry. Nitrogen trifluoride can be synthesized by passing a current through a high-temperature mixture of ammonium fluoride and hydrogen fluoride, with hydrogen gas as a byproduct.
