Answer:

Hydrogen sulfide reacts with aqueous selenous acid to produce selenium disulfide:

H2SeO3 + 2 H2S → SeS2 + 3 H2O

Selenium disulfide consists of 8-membered rings. It has an approximate composition of SeS2, with individual rings varying in composition, such as Se4S4 and Se2S6. Selenium disulfide has been used in shampoo as an antidandruff agent, an inhibitor in polymer chemistry, a glass dye, and a reducing agent in fireworks.[15]

Selenium trioxide may be synthesized by dehydrating selenic acid, H2SeO4, which is itself produced by the oxidation of selenium dioxide with hydrogen peroxide:[17]

SeO2 + H2O2 → H2SeO4

Hot, concentrated selenic acid can react with gold to form gold(III) selenate.[18]

Describe the formation of an aqueous libr solution when solid libr dissolves in water
steposvetlana [31]

Answer and Explanation:

The water is a polar solvent which dissolves into the LiBr molecules and converts into Li^+ and Br^- ions far from the solid also into the solution, when they are hydrated.

Now, the complete words are as given below:-

The K^+ and I^- ions at the surface of the solid are pulled into the solution by the polar water molecules, where the hydration process surrounds separate ions with water molecules.
