___________ would albumin expect to dissociate into individual ions and increase the number of osmols/mol in solution.
Lubov Fominskaja [6]

Answer: Check explanation please.

Explanation:

Before diving into the question,let us consider some important facts and definitions.

WHAT IS OSMOLARITY? Osmolarity is the number of OSMOLES of solute per litre of the solution. The unit of osmolary is OSMOLE. Nowadays, osmolarity has become a term used in the past, now osmolarity is called osmotic concentration.

OSMOLARITY can be calculated using; Σ(osmotic coefficient × number of ion × the solute molar concentration).

BACK TO THE QUESTION; ALBUMIN is a PROTEIN. Protein is a large molecule and it contributes an insignificant amount to osmolarity(around 0.6 Mosmole/litre).

Also, if we have the osmotic coefficient to be between zero and one, there is going to be great DISSOCIATION.

water is considered as a compound of hydrogen and oxygen and not a mixture of hydrogen and oxygen and comment on it
HACTEHA [7]
Wat is considered a compound of hydrogen and oxygen and not a mixture because hydrogen and oxygen have gone through a chemical process to form the compound h2O. A mixture can generally be easily separated whereas a compound must undergo another chemical process to separate its elements. Therefore to separate oxygen and hydrogen from water a chemical process is necessary.

A. Phenol (C6H5OH) is an aromatic compound and a colourless liquid widely used in household products
Olin [163]

Because there are 2 Cl on the left, we will put a coefficient 2in front of HCl on the right side to balance out the Cl. This would result in an unequal amount of H, with 6 on the right side and 7 in the left, so we have to put a coefficient of 2 in front of C6H5OH and C6H4OH on both sides to balance out the H. By doing this, we would obtain an equal amount of H on both sides. The Carbon is already balanced, and so is the Oxygen.

The hydrogen halide gases all have the same general formula, HX, where X can be a halogen (F, CI, Br, or I). HCl 2 effuses times
Natali [406]

Answer:

Explanation:

We collected the gas over water; to obtain the true pressure of the gas, we have to correct for the vapor pressure of water. We look up the vapor pressure of water at 24 ºC: 24 torr. The pressure of the evolved gas is, therefore, 738 −24 = 714 torr. 2. We want the molar mass of the
