Ammonium hydrogen sulfide (NH4HS) can decompose to ammonia and hydrogen sulfide: Upper N upper H subscript 4 upper H upper S (s) double-headed arrow upper N upper H subscript 3 (g) plus Uppe H subscript 2 upper S (g). What is the equilibrium constant expression for this system? K subscript e q equals StartFraction StartBracket upper N upper H subscript 3 EndBracket StartBracket upper H subscript 2 upper s EndBracket over StartBracket upper N upper H subscript 4 upper H upper S EndFraction. K subscript e q equals StartBracket upper N upper H subscript 3 EndBracket StartBracket upper H subscript 2 upper s EndBracket. K subscript e q equals StartFraction 1 over StartBracket upper N upper H subscript 3 EndBracket StartBracket upper H subscript 2 upper s EndBracket EndFraction.

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
