Predict whether each of the following is soluble in water or not.
wlad13 [49]

Answer:

The soluble in water are a and b. c is not soluble in water

Explanation:

The water solubility of a compound, it depends its polarity (. KHSO4 has several polar molecules, actually it has ions charged positively like K and H, and charged negatively like sulfate (SO4-2). When it happens, molecules can do hydrogen bridges with water. It is because of above, KHSO4 can be used in wine making. Something similar happens with propylen glycol but in this case the polar part is OH- ions. Benzene has not polar parts. It is totally apolar compound.

I hope my answer helps you

Calculate the osmotic pressure at 25°C across a semipermeable membrane separating seawater (1.14 M total particles) from a 0.503
liq [111]

Answer:

The osmotic pressure is 24.6 atm

Explanation:

π = M . R . T . i → Formula for osmotic pressure

i = 2 ⇒  NaCl →  Na⁺ + Cl⁻

i means Van't Hoff factor, which indicates the numbers of ions dissolved, by the stoichiometry.

R → Universal gases constant

T→ T° in K → T°C + 273 → 25°C + 273 = 298K

π = Osmotic pressure

Let's replace data given ⇒ π = 0.503 mol/L . 0.082L.atm/mol.K . 298K .2

π = 24.6 atm
