Chilean niter deposits are mostly sodium nitrate, but they also contain 0.3%iodine in the form of calcium iodate, Ca(IO3)2. After the sodium nitrate inthe niter is dissolved and recrystallized, the remaining solution contains 9 g/Lsodium iodate, NaIO3(aq). The NaIO3 is converted to iodine when it reactswith sulfur dioxide and water.2NaIO3 + 5SO2 + 4H2O → Na2SO4 + 4H2SO4 + I2a. How many liters of sodium iodate solution that contains 9 g of NaIO3 perliter would be necessary to form 127.23 kg of iodine, I2?b. What mass, in megagrams, of Chilean niter that is 0.3% I would benecessary to form the volume of sodium iodate solution you calculated inpart (a)

The fizz produced when an Alka-Seltzer tablet is dissolvedin water is due to the reaction between sodium bicarbonate(NaHCO3) and citric acid (H3C6H5O72)3 NaHCO3(aq) + H3C6H5O7(aq)-------->3 CO2(g) + 3H2O(l) + Na3C6H5O7(aq) In a certain experiment 1.00 g of sodium bicarbonate and1.00 g of citric acid are allowed to react. The actual yield of CO2 was 0.436 g. a.) What is the theoretical yield of CO2? b.) What is the % yield?
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?
There are two steps in the extraction of copper metal from chalcocite, a copper ore. In the first step, copper(I) sulfide and oxygen react to form copper(I) oxide and sulfur dioxide: →+2Cu2Ss 3O2g + 2Cu2Os 2SO2g In the second step, copper(I) oxide and carbon react to form copper and carbon monoxide: →+Cu2Os Cs + 2Cus COg Suppose the yield of the first step is 86.% and the yield of the second step is 64.% . Calculate the mass of copper(I) sulfide required to make 2.0kg of copper. Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits.
