The Henry's Law constant for N2 gas in water at 25 oC is 0.00068 mol/L-atm. Calculate the solubility of N2 in water at 25 oC in moles/L if the partial pressure of N2 in the headspace above a water sample is 1.83 atm.
butanoic acid and 0.01 M NaCl. The ionization constant of butanoic acid is Ka = 1.52 × 10-5. Take the size of C3H7COO- to be 500 pm.
Potassium hydroxide is used to precipitate each of the cations from their respective solution. Determine the minimum concentration of KOH required for precipitation to begin in each case.
the side of the coil which cuts magnetic flux link from the north pole first becomes the live wire. Is there any reason behind that or is it just a natural phenomena?
Calculate the pressure and temperature at which 1.0 mol of H2O, HCl, and C6H6 corresponds to the same states as 1.0 mol of CH4 at 2.00 atm and 298
Calculate the radiation dosage (in grays) for an 85-kg person that is exposed for 7.0 seconds to a 3.0 Ci source of beta radiation. Assume that 100% of the radiation is absorbed and each beta particle has an energy of 1.7× 10-13 J.
How many non-bonding valence electrons are there in a molecule of fumaric acid?
The initial concentrations of Pb2+ and Ag+ are 0.05M and for Cl- 1.5M. Assume all the present Pb2+ and Ag+ precipitate out of solution. Use the remaining Cl- concentration and the Ksp and Kf reactions for AgCl and AgCl2-, respectively, to determin..
