Ammonium hydrogen sulfide (NH4HS) can decompose to ammonia and hydrogen sulfide:

NH4HS(S) ↔️ NH3(g)+H2S(g)

What is the equilibrium constant expression for
this system?
ANSWER: B

According to the vsepr theory what is the shape of a molecule that has a central atom valence three other items with no lone pairs of electrons

Most materials are not magnetic because their magnetism has worn off. their magnetic domains are arranged randomly. they lack magnetic fields. earth’s heat has destroyed their magnetism.

Consider the reaction of a(g) + b(g) + c(g) => d(g) for which the following data were obtained: experiment initial [a], mol/l initial [b], mol/l initial [c], mol/l initial rate, mol/l.s 1 0.0500 0.0500 0.0100 6.25 x 10^-3 2 0.100 0.0500 0.0100 2.50 x 10^-2 3 0.100 0.100 0.0100 1.00 x 10^-1 4 0.0500 0.0500 0.0200 6.25 x 10^-3 what is the rate law for the reaction?
