Answer:
Explanation:
a) Volume of the gas nRT / P
= 1,04 X 8.3 X 298 / 11 X 10⁵ m³
= 233.85 x 10⁻⁵ m³
= 233 x 10⁻² L
2.33 L
P₁V₁ / T₁ =P₂V₂/T₂
(11 X 2.33) / 298 = (1 X 24.2) / T
T = 281.37 K
= 8.37 degree
b ) w = p x change in volume
= 10⁵ x ( 24.2 - 2.33 ) x 10⁻³ J
= 21.87 X 10² J
2187 J
q = n x Cp x (25 - 8.37 )
= 1.04 x 35.66x 16.63 J
= 616.65 J
ΔU = Q - W
= 616.65 - 2187 J
= - 1570.35 J

Answer is: osmotic pressure.
The direction of osmotic pressure is always from the side with the lower concentration of solute to the side with the higher concentration, in this example, from solution b (5% glucose) to solution b (25% glucose).
Osmotic pressure, alongside the vapor pressure depression, freezing point depression and the boiling point elevation are the colligative properties od solution.
4.2 × 10²² atoms Al × (1 mol Al / 6.022 × 10²³) = moles Al
Last one: fraction 1 mole Al over 6.022 × 10²³ atoms Al
Answer:
Phase changes typically occur when the temperature or pressure of a system is altered. When temperature or pressure increases, molecules interact more with each other. When pressure increases or temperature decreases, it's easier for atoms and molecules to settle into a more rigid structure.
