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?

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

the answer to this question is 3.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
