One mole of N2 and three moles of H2 are placed in a flask at 375 C. Calculate the total pressure of the system at equilibrium if the mole fraction of NH3 is 0.21. The Kp for the reaction is 4.31*10^4.
Calculate ?Grxn at 298 K under the conditions shown below for the following reaction. SO3(g) + H2O(g) ? H2SO4(l) ?G°= -90.5 kJ P(SO3) = 0.20 atm, P(H2O) = 0.88 atm
The voltage of the cell is 1.74 V, with metal X as the positive electrode. Calculate the standard reduction potential for the X half-reaction. The standard reduction potential of the copper half-reaction is 0.52 V
The compound K2SiO 3 • χH2O is a hydrated crystal. It is analyzed for percent water in a procedure similar to the laboratory assignment with barium chloride
consider a gas-phase reaction 2a-> r 2s with unknown kinetics. if a space velocity of 1/min is needed for 90% conversion of a in a plug reactor, find the corresponding space-time and mean residence time or holding time of fluid in the plug flow re..
At a given temperature, 0.150 mol NO, 0.100 mol Cl2, and 0.250 mol ClNO were placed in a 10.0 L container. The following equilibrium is established
Complete the ground-state electron configuration for these ions (using the noble gas abbreviation) and identify the charge. we need to find the electron configuration and the charge for Zinc ion thallium(lll) ion
The nucleus of an atom accounts for... A-most of the size and mass of the atom. B-very little of the size and mass of the atom. C-most of the atom\'s size but very little of its mass. D-most of the atom\'s mass but very little of its size.
water is to be pumped from a lake to a tank uphill that is open to the atmoshpere. the flow rate of water is 10 liters
15.0 moles of gas are in a 6.00 L tank at 24.1 degrees C. Calculate the difference in pressure between methane and an ideal gas under these conditions. The van der Waals constantsfor methane are a = 2.300 L^2 atm/ mol^2 and b = 0.0430 L/mol
According to NMR spectra rules, a carbon that is more substituted is more deshielded. For some reason I cannot understand this, because in my mind I see it has more shielding since there is more electron density around it. Please explain in detail..
A solution consisting of .200 mol of methylbenzene (C6H5CH3) in 250 g of nitrobenzene (C6H5NO2)freezes at .40 degrees celsius
A tank contains N2 at 1.0 atm and O2 at 2.0 atm. Helium is added to this tank until the total pressure is 6.0 atm. What is the partial pressure of the helium?
