A mixture of gases contains 7.5g hydrogen and 29.6 nitrogen with a total pressure of 127 torr. Calculate the solubility of nitrogen gas if Henry's constant is \(6.1*10^-4 M/atm\)
Calculate the pressure difference between CH4 and an ideal gas under these conditions. The van der Waals constants for CH 4 are a=2.300L2⋅atm/mol2 and b=0.0430 L/mol.
Determine how long will it take for a sample of N2O5 to decay to sixty percent of its initial value?
In a voltaic cell, the anode is negative relative to the cathode. Oxidation occurs at the anode of either type of cell (voltaic and electrolytic).
Determine how many moles of SO 3 are formed if 12.24 moles of O 2 react with excess SO 2 ,? use the balance equation given as 2SO 2 (g)+O 2 (g)----> 2SO 3 (g)
What is the pH of pure water in equilibrium with 1 atmosphere of carbon dioxide at 25?C?
If 27.2 mL of NO2 gas is completely converted to N2O4 gas under the same conditions, what volume will the N2O4 occupy?
The dispersion of a diffraction grating, such as the one shown at the right, is the angle of separation per μm of wavelength, Î"Φ /Î"λ
Isopropyl alcohol is mixed with water to produce a 31.0% (v/v) alcohol solution. How many milliliters of each component are present
After you have made your observations, you can release the vacuum and allow the pressure inside to return to atmospheric pressure. Do this by removing the pumper and squeezing the rubber septum as indicated.
A mixture of 0.10 mol of NO(g), 0.05 mol of H2(g), and 0.10 mol of H2O(g) is placed in a 1.0-L vessel at 300K?
When a chiral carbon contains a hydrogen, you should not show the hydrogen, but you must use either a wedge or dashed bond and 2 sticks to establish stereochemistry.
A stock solution is prepared by adding 21 mL of 1 M AlCl3 to enough water to make 76 mL. What is the Cl- concentration of 40 mL of the stock solution?
