Problem- Ammonium hydrogen sulfide dissociates into ammonia and H2S. If solid NH4HS is placed in an evacuated flask at a fixed temperature it will dissociate until the total gas pressure is 500 torr. If additional ammonia is introduced into the equalibrium mixture without changing the temperature until the pressure is 700 torr, what is the partial pressure of H2S under these conditions? What is the final total pressurein the flask when the new equalibrium is reached?

A 1.000L sample has HCL gas at 25 C and 732.0mm HG was absorbed completely in an aqueous solution that contained 6.954g of Na2CO3and 250.0 g water.
Assume that the wet limestone process requires 1 metric ton of CaCO3 to remove 90% of the sulfer from 4 metric tons of coel containing 2% S. Assume that the sulfur product is CaSO4. Calculate the percentage of the limestone converted to calcium su..
The decay of radioactive elements follows first-order kinetics. Therefore, the rate of decay can be described by the same integrated rate equations and half-life equations that are used to describe the rate of first-order chemical reactions.
Problem- Derive the integrated rate expression for a reaction that is 1/2 order in {A}. Also, derive an expression for t1/2.
