Consider the following reaction in chemical equilibrium:
2 BrNO(g) ? 2 NO(g)+ Br2(g)
What is the effect of adding additional Br2 to the reaction mixture? What is the effect of adding additional BrNO?
2. At 70 K, CCl4 decomposes to carbon and chlorine. The Kp for the decomposition is 0.76. Find the starting pressure of CCl4 at this temperature that will produce a total pressure of 1.0 atm at equilibrium.
Assuming that none of the intermediates have appreciable concentrations, what are the values of C61206, O2, CO2, and H20, given that the overall rate is 1X10^-4 mol/L*S. Assume there is an excess of oxygen in the system.
Calculate the mass percent of copper(II) sulfate pentahydrate in the recovered sample.
The buret is filled with the NaOH titrant and the initial volume reading is immediately recorded without waiting the recommended 10-15 seconds.
The equilibrium constant, Kp is 0.15 at 298 k for the reaction N2O4(g) 2 NO2(g) If the total pressure of the gas mixture at equilibrium
water at 20 degrees celsius is flowing with velocity of 0.5 ms between two parallel flat plates placed 1 cm apart.
You have a polypeptide that has been degraded with cyanogens bromide and trypsin. The sequences of the fragments are listed below. What is the sequence of the full polypeptide chain
Draw the structure of the two tertiary (3°) alcohols with the molecular formula C7H16O that contain a one-carbon branch
Crude gunpowders often contain a mixture of potassium nitrate and charcoal (carbon). When such a mixture is heated until reaction occurs, a solid residue of potassium carbonate is produced.
Problem- Consider the titration of 300.0 mL of 0.556 M NH3 (Kb = 1.8 x10-5 ) with 0.500 M HNO3. After 150.0 mL of 0.500 M HNO3 has been added, what is the pH of the solution
A quantity of N2 gas originally held at 5.21atm pressure in a 1.00-L container at 26 deg C is transferred to a 12.5-L container at 20 deg C. A quantity of O2 gas originally at 5.21atm and 26 deg C in a 5.20-L container is transferred to this same ..
A sample of nitrogen of mass 3.12 g at 23 C is allowed to expand reversibly and adiabatically from 400 cm^3 to 2 dm^3
The student next added 3M KOH solution to the aqueous solution and Mg(OH)2 precipitated. After filtering the solution and drying the precipitate, the student recovered 1.10g of Mg(OH)2. Calculate the percent Mg(OH)2 in the mixture
