Why is it preferable to "use nuclear binding energy per nucleon for a comparison of the stabilities of different nuclei?
what would be the proper sequence for the following compounds to be listed from highest melting point to least?
The vapor pressure of liquid Ni is 0.100 torr at 1606 degrees C and 1.00 torr at 1805 degrees C. The molar heat of fusion of Ni is 3.25 kcal/mol. Determine the vapor pressure of solid Ni at 1200 degrees C.
A protein has a net charge of +2 in an electric field at pH 4.5. What is the frictional drag experienced by the protein if it moves at a velocity of 0.0018 m/sec and the electric field strength is 10 J/C·m. Units for frictional drag should be in k..

Why must the spot applied to a TLC plate be above the level of the developing solvent
Calculate the solubility of silver chloride in a solution that is .100 M in NH3. Ksp for AgCl = 1.77x10^-10. Kf for Ag(NH3)2+ = 1.7x10^7
How many Grams of NH3 are consumed when 12.5 grams of 02 react completely in the following equation? I am not sure exactly how to solve this.
A solution is prepared that initially contains 0.10 M Ag+(aq) and 0.80 M NH3 (aq). The Kf for the formation of Ag(NH3)2+(aq) is 1.7 x 10^7. Write the equilibrium equation that represents the formation of this complex ion.
