Explanation:

A and D

A. A pressure equal to that of the osmotic pressure will result in reverse osmosis.

D. The movement of the solvent particles from the concentrated solution to the dilute solution is known as reverse osmosis.

During osmosis, water molecules from the less concentrated right side, will flow into the left side til they equilibrate- at equilibrium both sides will have the same concentration of solute.

Thus, the water passes through the membrane due to the difference in osmotic pressure/ solute concentration on either side of the membrane, this means that the water moves from regions of high osmotic pressure/concentration to regions of low osmotic pressure /concentration.

Water potential equal to the pressure potential shifts the equilibrium, resulting in the movement of solute.

However, in reverse osmosis, solute molecules move from regions of high solute concentration, to regions of low solute concentration across the membrane.

Answer:

Mass and length

Explanation:

An extensive property is a property of matter that changes as the amount of matter changes. Like other physical properties, an extensive property may be observed and measured without any chemical change (reaction) occurring.

jek_recluse [69]

The question is incomplete, the complete question is:

A certain substance X has a normal freezing point of $-6.4^oC$ and a molal freezing point depression constant $K_f=3.96^oC.kg/mol$ . A solution is prepared by dissolving some glycine in 950. g of X. This solution freezes at $-13.6^oC$ . Calculate the mass of urea that was dissolved. Round your answer to 2 significant digits.

<u>Answer:</u> The mass of glycine that can be dissolved is $1.3\times 10^2g$

<u>Explanation:</u>

Depression in the freezing point is defined as the difference between the freezing point of the pure solvent and the freezing point of the solution.

The expression for the calculation of depression in freezing point is:

$\text{Freezing point of pure solvent}-\text{freezing point of solution}=i\times K_f\times m$

OR

$\text{Freezing point of pure solvent}=\text{Freezing point of solution}=i\times K_f\times \frac{m_{solute}\times 1000}{M_{solute}\times w_{solvent}\text{(in g)}}$ ......(1)

where,

Freezing point of pure solvent = $-6.4^oC$

Freezing point of solution = $-13.6^oC$

i = Vant Hoff factor = 1 (for non-electrolytes)

$K_f$ = freezing point depression constant = $3.96^oC/m$

$m_{solute}$ = Given mass of solute (glycine) = ?

$M_{solute}$ = Molar mass of solute (glycine) = 75.07 g/mol

$w_{solvent}$ = Mass of solvent = 950. g

Putting values in equation 1, we get:

$-6.4-(-13.6)=1\times 3.96\times \frac{m_{solute}\times 1000}{75.07\times 950}\\\\m_{solute}=\frac{7.2\times 75.07\times 950}{1\times 3.96\times 1000}\\\\m_{solute}=129.66g=1.3\times 10^2g$

Hence, the mass of glycine that can be dissolved is $1.3\times 10^2g$
