Ammonium Hydrogen Sulfide NH4HS

If 20.0 g of ammonium hydrogen sulfide [NH4HS(s)j is placed in a 10.0 L evaeuated container at 395 K, ealeulate the equilibrium partial pressures of ammonia (NH3) and hydrogen sulfide (H2S) and determine the amount of NH4HS(s) left in the container. 

The decomposition of ammonium hydrogen sulfide NH4HS( ) 5=t NH3(g) + HzSlg)... 

Sf 15.74 The decomposition of ammonium hydrogen sulfide NH4HS(s) 5=t NH3(g) + H2S(g) is an endothermic process. A 6.1589-g sample of the sohd is placed in an evacuated 4.000-L vessel at exactly 24 C. After equihbrium has been established, the total pressure inside is 0.709 atm. Some solid NH4HS remains in the vessel, (a) What is the Kp for the reaction (b) What percentage of the solid has decomposed ... 

Ammonium hydrogen sulfide, NH4HS(s), used as a photographic developer, is unstable and dissociates at room temperature. 

Ammonium hydrogen sulfide, a solid, decomposes to give NH3(g) and H2S(g). At 25°C, some NH4HS(s) is placed in an evacuated container. A portion of it decomposes, and the total pressure at equilibrium is 0.659 atm. Extra NHslg) is then injected into the containei and when equilibrium is reestablished, the partial pressure of NH3(g) is 0.750 atm. 

AMMONIUM MONOSULFIDE (12124-99-1) NH4 HS (aqueous) (NH4)2S (anhydrous) The anhydrous material is pyrophoric in air it decomposes at room temperature, releasing ammonia and toxic and flammable hydrogen sulfide gas. Stable below 32°F/0°C. The commercial product [a 40% solution in water (NH4HS)] is stable. The aqueous solution is a reducing agent. Violent reaction with strong oxidizers...
