The apparatus consists of two sets of bulbs. The first set of three bulbs is filled with solution to half of their capacity and second set of another three bulbs is filled with the pure solvent. Each set is separately weighed accurately. Both sets are CONNECTED to each other and then with the accurately weighed set of guard tubes filled with anhydrous calcium chloride or some other dehydrating agents like P2O5, conc. H2SO4 etc. The bulbs of solution and pure solvent are kept in a THERMOSTAT maintained at a CONSTANT temperature.

A current of pure dry air is bubbled through. The air gets saturated with the vapours in each set of bulbs. The air takes up an amount of vapours proportional to the vapour pressure of the solution first and then it takes up more amount of vapours from the solvent which is proportional to the difference in the vapour pressure of the solvent and the vapour pressure of solution, i.e. p0–ps. The two sets of bulbs are weighed again. The guard tubes are also weighed.

Loss in mass in the solution bulbs ∝ps

Loss in mass in the solvent bulbs ∝(p0–ps)

Total loss in both sets of bulbs ∝[ps+(p0–ps)]∝p0

Total loss in mass of both sets of bulbs is EQUAL to gain in mass of guard tubes.

Thus, p0−psp0=Loss in mass in solvent bulbsTotal loss in mass in both sets of bulbs=Loss in mass in solvents bulbsGain in mass of guard tubes
Further we know from Raoult’s law

p0−psp0=wAmAwAmA+wBmB
The above relationship is USED for calculation of molecular masses of non-volatile solutes.

Supramolecular chemistry is the domain of chemistry beyond that of molecules that focuses on the chemical systems made up of a discrete number of assembled molecular subunits or COMPONENTS. The forces responsible for the spatial ORGANIZATION may vary from weak (intermolecular forces, electrostatic or hydrogen bonding) to strong (covalent bonding), provided that the degree of electronic COUPLING between the molecular component remains small with respect to relevant energy parameters of the component.[8][9] While traditional chemistry focuses on the covalent BOND, supramolecular chemistry examines the weaker and reversible noncovalent interactions between molecules.[10]. These forces include hydrogen bonding, metal coordination, hydrophobic forces, van der Waals forces, pi-pi interactions and electrostatic effects

Question_answer ANILINE react with acetaldehyde to FORM. A) Schiffs base. B) carbyl amine. C) immine. D) none of these. Studyadda. PREVIOUS Next. Correct Answer: A. Solution :.

Hi......
As there is an increase in length, there is also an increase in the RESISTANCE
The FORMULA of Resistance (R) = RESISTIVITY (r) × length (l) / Area (A)
So, the NEW resistance =R+1/100R
=R+R/100
=(100R +R) /100
=101 R /100
new resistance =1.01 R

Olá User!
Here's ur answer.

⏩ Chemical Formula : It is a representation of a SUBSTANCE using SYMBOLS for its constituent elements.

The chemical formula is an EXPRESSION which STATES the number and types of atoms PRESENT in a molecule.

Hope it helps!!

The ELEMENT is BROMINE.

All of these..........

Molecules of solids are very TIGHTLY PACKED and it can't be compressed anymore

But there is large spaces between the molecules of LIQUID and gases, so it can be compressed

When evaporation occurs then the liquid (MOSTLY water) absorbs all the HEAT from the surroundings and take it with it and we feel cool. evaporation causes cooling effect because the heat energy is absorbed by SURROUNDING particles.

Hey MATE.....☺

Here's ur ans ⬇

The INSECTICIDE containing 99% /GAMMA - isomer of BENZENE hexachloride is known as Methoxychlor.

✨Hope it HELPS

Hey mate here's your ANSWER.....

This is because there is WEAK force of ATTRACTION between PARTICLES of liquid and gases whereas it is not the condition with solids.

Hope it helps ☺️

Hey mate.....☺

Here's ur ans.⬇

↪ Sulpha DRUGS are USED for removing bacteria .
..

THEREFORE , B option is RIGHT

✌Hope it helps

The only one who can help me with that GAY and I can help you get the money from BANARAS is not QUESTIONS is it a good TIME

Yes U can TREAT it as a vapour SIMCE vapour are ALSO in gaseous state

Hii MATE, here's UR answer.
ACCORDING to me the answer should be (D)The Molar solubility of MY in water is LESS than that of NY

I Hope It Helps.....☺️

Assign an OXIDATION number EQUAL to the charge on the CATION (H+), so that the SUM of all of the oxidation NUMBERS will equal 0. 8. N2O5.
N = +5, O = -2.

I THINK that C is the CORRECT ANSWER

I THINK that A is the CORRECT ANSWER

What is your's QUESTION i don't UNDERSTAND...

Simply..

Rayon and acetate are both artificial FIBERS, but not truly SYNTHETIC, being MADE from wood. NYLON, the first synthetic fiber in the "fully synthetic" sense of that term, was developed byWallace Carothers, an American researcher at the chemical firm DuPont in the 1930S.

Here your answer plz.
hy is PYRENE have 0.135mg/l but the naphthalene is insoluble in WATER .
note = naphthalene are only soluble in BENZENE .
I HOPE it is CLEAR to you.

Titanium, which is ALREADY used ubiquitously for IMPLANTS, was chosen as the alloying element because of its PROVEN biocompatibility and corrosion resistance in physiological ENVIRONMENTS. Thus, alloying magnesium with titanium is EXPECTED to improve the corrosion resistance of magnesium.
