Sulfur is used in the production of vulcanized rubber, detergents, dyes, pharmaceuticals, insecticides, and many other substances. The final step in the Claus method for making sulfur isSO2(g) + 2H2S(g) ==> 3S(s) + 2H2O(l)
a) What minimum volume of sulfur dioxide at STP would be necessary to produce 82.5 kg of sulfur?
b) What maximum mass of sulfur in kg could be produced by the reaction of 1.3 x 10 4(the 4th) m3 of SO2(g) with 2.5 x 10 4(the 4th) m3 of H2S(g), both at STP?

These are characteristics of the titration curve for 25.0 mL of 0.400 M NH3(aq) titrated with 0.335 M HI(aq). (For NH3, Kb = 1.8x10-5.) (1a) The initial pH
What is the pH of a solution containing 0.24 moles of ammonia and 17.8g of ammonium chloride, NH4Cl. Kb for ammonia is 1.8 times 10, What is the PH of a 0.085M solution of ammoniun chloride. Kb for ammonia is 1.8 times 10
2,3-dimethyl-2,3-butanediol upon heating in aqueous acid, rearranges to form 3,3-dimethyl-2-butanone. Suggest a mechanism for this
The solute increases the volume of the solution, and an increase in volume requires an increase in the temperature to reach the boiling point (derived from PV = nRT).
