Calculate the root-mean-square speed of Ne atoms in m/s. My main problem is in converting the average kinetic energy of NH3 at 70 C to average kinetic energy of NH3 at 68 C?
Compound Y has a solubility of 2.0 g/100 mL in water and 20.0 g/100 mL in ether. What weight of compound Y would be removed from a solution of 1.8 g of Y in 100 mL of water by a single extraction with 100 mL of ether?
The vapor pressure of benzene (C6H6) is 40.1 mm Hg at 7.6 C. The delta H vap=31.0 KJ/mol, what is benzene's vapor pressure at 60.6 C?
weak base so you must consider other equilibria. (Ksp(ZnC2O4)=7.5X10^-9, Kb1=1.8X10^-10, Kb2=1.8X10^-13). Solve using systematic treatment of equilibrium.
A packed tower is used to purify a gas containing 4 mole % of H2S. The total inlet gas flow to the tower is 75 kmol/h and the total inlet pure solvent flow to be used to absorb the H2S is 95 kmol /h.
commercial concentrated aqueous ammonia is a solution of 28.0%, by mass, ammonia, NH3, (molar mass=17.0 g/mol) in water. the density pf the solution is .900g/mL.
One of the treatments for gangrene and the bends, is hyperbaric oxygenation. This occurs in a chamber in which oxygen is used at higher-than-normal pressures.
