Does molal elevation constant depend on nature of solvent?
This is a colligative property which does not depend on the nature of solute is the molal boiling point elevation constant or ebullioscopic constant of the solvent.
What is meant by constant molal overflow?
Constant molal overflow is a term used in binary distillation. When a 2 component mixture is being separated in a distillation column,the assumption of constant molal overflow means assuming that both components have the same enthalpy. It assumes that one mole of component 1 when it condenses will vapourise 1 mole of component 2,also assumes no heat loss from the column. Can be wildly innacurate,particularly with separating organic solvents,and water. Water has a uniquely high enthalpy,often 5-6 times higer than the organic solvents.
What is the freezing point depression constant for naphthalene?
The freezing point depression constant for Naphthalene is 6.9 degrees Celsius/mhttp://en.wikipedia.org/wiki/Freezing-point_depression
The molal freezing point constant kf is a property of the solvent not the solute What does this say about the fact that freezing point depends on the amount of solute rather than solute's nature?

How 1 molal urea solution is equal to 0.5 molal NaCl solution?
Uric acid is an entirely different compound than salt, so I do not see how there is an equivalence between the two.

Can constant emotional stress cause depression?
Yes, if you are constantly abused or emotionally stressed, that can lead to things that would eventually lead to depression or bipolar disorder.

How will determine Molecular weight by Landsberger method?
we can determine the molecular weight from landsberger experiment for elevation of boiling point by using the formula M2=(KBW2)*1000/T'W1 where M2=molecular mass Kb=ebullioscopic constant or molal boiling point constant W2=mass of solute W1=mass of solvent T'=change in temprature
What exactly causes chronic pain in clinical depression?
It common for people with chronic pain to sometimes suffer from depression. Constant pain and no relief for the pain will cause depression because of the time spent worrying and obsessing over the pain.
Which is more concentrated one molar NaCl or one molal NaCl?
They are equivalent. Molal is now an obsolete, not recommended term.
