Question

Elemental sulfur is one of the products of the gas-phase reaction of nitric acid and hydrogen sulfide. The other

products are nitrogen monoxide(g) and water(g). A
container and hydrogen sulfide (s) are massed and found to
be 23.3 g. To this container 8.50 L of nitric acid gas was
introduced. After the reaction the solid was extracted and
found to weigh 16.8 g. (mass of container is 5.10g )
Based on this result find:
a. the percent yield of the solid product
b. the amount of the other products produced
c. the name of the solid produced

Answer 1

The manufacturing processes for liquefied petroleum gas are designed so that the majority, if not all, of the sulfur compounds are removed. The total sulfur level is therefore considerably lower than for other crude oil-based fuels and a maximum limit for sulfur content helps to define the product more completely. The sulfur compounds that are mainly responsible for corrosion are hydrogen sulfide, carbonyl sulfide and, sometimes, elemental sulfur. Hydrogen sulfide and mercaptans have distinctive unpleasant odors. A control of the total sulfur content, hydrogen sulfide and mercaptans ensures that the product is not corrosive or nauseating. Stipulating a satisfactory copper strip test further ensures the control of the corrosion.
