The first step in industrial nitric acid production is the catalyzed oxidation of ammonia. Without a catalyst, a different reaction predominates:
4NH3(g) + 3O2(g) â‡" 2N2(g) + 6H2O(g)
When 0.0200 mol gaseous NH3 and 0.0180 mol gaseous O2 are placed in a 1.00 L container at a certain temperature, the N2 concentration at equilibrium is 2.20Ã-10-3 M.
Calculate Keq for the reaction at this temperature.
calculate the pH of the 1 L solution of 0.25 M TRIS plus the addition of 0.05 M HCL. Show how many moles of TRIS and TRIS HCL are present after the addition of the HCL. Use the Henderson Hasselbalch equation to calculate the pH?
A 28.0-g sample of water at 260. K is mixed with 51.0 g water at 310. K. Calculate the final temperature of the mixture assuming no heat loss to the surroundings
calculate the concentration in mol/L and mg/L of a solution prepared by adding 4.00 mL of a 8.26 x 10^-4M stock solution of Allura Red to a 100.00 mL volumetric flask and then filling to the mark with DI water.
Concrete used in road construction is reinforced using steel bars in a grid, known collectively as "rebar." After many years, rebar will begin to corrode, and the concrete will weaken.
A sample of nitrogen gas is collected over water at a temperature of 23.0 degrees Celcius. What is the pressure of the nitrogen gas if atmospheric pressure is 785 mm Hg?
Write the expression for the equilibrium constant, Kb, for methylamine also compute the molar concentration of OH- in the 50.0 mL sample of the CH 3 NH 2 solution.
1) Prions are smaller than viruses, which are affected by radiation. 2) Prions do not contain genetic information, which is affected by ionizing radiation.
at 400 K, the rate of decomposition of a gaseous compound initially at a pressure of 12.6 kPa, was 9.71 Pa/s when 10.0 % had reacted and 7.67 Pa when 20.0 % had reacted.Determine the order of reaction.
Consider a gas at 1.00 atm in a 5.00 L container at 20 degrees celsius. What pressure does the gas exert when transferred to a volume of 2.77 L at 43 degrees celsius?
Design a qualitative analysis scheme
The formal charge on the P atom is zero and It is best described with three resonance structures.
50.0 ml of 2.00M H2SO4 react with 75.O ml of 2.00M NaOH.Identify the limiting and excess reactants.
