The osmotic pressure of the glucose solution is 21.49 atm.
From the question given above, the following data were obtained:
- Molarity (M) = 0.85 M
- Temperature (T) = 35 °C = 35 + 273 = 308 K
- Van't Hoff's factor (i) = 1 (non-electrolyte)
- Gas constant (R) = 0.0821 atm.L/Kmol
- Osmotic pressure (π) =?
π = iMRT
π = 1 × 0.85 × 0.0821 × 308
π = 21.49 atm
Therefore, the osmotic pressure is 21.49 atm

Answer:
The nuclear charge increases from boron to carbon, but there is no additional shielding( that is no additional shells).
Explanation:
First of all, we must know the electron configuration of carbon and boron.
Boron- 1s2 2s2 2p1
Carbon- 1s2 2s2 2p2
Moving from boron to carbon, the effective nuclear charge increases without a corresponding increase in the number of shells. Remember that shielding increases with increase in the number of intervening shells between the outermost electron and the nucleus. Since there isn't an increase in shells, boron experience a lower screening effect.
From
Zeff= Z- S
The Z for carbon is 6 while for boron is 5 even though both have the same number of screening electron S(4 screening electrons). Hence it is expected the Zeff(effective nuclear charge) for boron will be less than that of carbon.
