3. Elemental sulfur is a molecular solid. The most stable allotrope of elemental sulfur is actually the eight-membered ring, Ss. Thus, the elemental sulfur in the H2S formation reaction shown in question 1 should actually be written as Sa(s). Use the equilibrium constant given in question 1 to find K for the following reaction: 8H2(g) + S«(s) - 8H2S(8) K ? 1. Ammonia and hydrogen sulfide...

Kc. I just don't understand how the small-x approximation applies
to this problem since it doesn't seem to follow the rules for x is
small approximation. I tried comparing the value of 0.097
M/9.30*10^-8 which was 1.0*10^6 which is smaller than 400 so the x
is small doesn't apply, however I can't seem to find another method
