Kp of NH4HS--->NH3+H2S is 7.00*10^-2 at 22C. A sample of NH4HS is placed in an evacuated container as well as allowed to come to equilibrium. The partial pressure of NH3 is then raised by the addition of 0.590atm of NH3. Explain the partial pressure of H2S at equilibrium is now what atm?
Show that the Slater determinant formalism automatically incorporates the Pauli exclusion principle by evaluating the He ground-state wave function of Equation 10.8, giving both electrons the same quantum numbers.
There are about 1,200,000 automobiles registered in Pine Bluff, AR. Each automobile emits 3.1 g NO2 and 1.6 g CH4 per vehicle mile. Each automobile travels 30 miles round trip per working day. What is the total volume in cubic meter of NO2 and CH4..
Water (2290g ) is heated until it just begins to boil. If the water absorbs 4.99×10^5J of heat in the process, what was the initial temperature of the water.
The sodium hydroxide solution was prepared by dissolving 10.00 g of solid NaOH in sufficient water to form 200.00 mL of solution. If the equivalence point was reached after the addition of 23.50 mL of the NaOH solution, what is the molarity of HNO..
A mixture of 1.374g of H2 and 70.31g of Br2 is heated in a 2.00 L vessel at 700 K. These substances react as follows: H2(g) + Br2(g) 2HBr(g) At equilibrium the vessel is found to contain 0.566g of H2.
