Ammonium hydrogen sulfide will decompose into ammonia gas and hydrogen sulfide gas when heated to a
constant temperature. Consider the equilibrium system
NH4HS) = NH3(g) + H2S)
which is developed from 2.00 mole of NH4HS in a
100. L cylinder. At equilibrium the total pressure is
found to be 0.600 atm. K, will be equal to
(A) 9.00 10-2
(B) 6.00 x 10-3
(C) 3.60 x 10-1
(D) 1.20

Can anyone explain 1. review your spectrometry data and use the known elements to identify the star's composition. which unknown elements make up this star? justify your element selections. 2. in parts i and ii of the lab, what happened to the electrons of each element to produce the different colors of light? explain your answers using important terms from the lesson and information provided in the laboratory. 3. stars composed of heavier (more massive) elements are often slightly older than stars made predominantly from hydrogen and helium. based on your data, is the newly discovered star a younger star? explain your answer.
