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
1 How much hydrogen sulfide is used in this experiment?

explanation:

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
