Answer:
c. estrogen > propanol > alanine > sodium
Explanation:
The phospholipid bilayer is formed by amphoteric lipids, the nonpolar region is inside the bilayer, so the diffusion of nonpolar molecules are easy (nonpolar reacts with nonpolar) and generally occurs passively (without loss of energy). With the increase of the polarity, the diffusion became difficult and slow. All the molecules are shown below.
Estrogen has two points of polarity in its hydroxides, but the carbon rings stabilize the molecule, and it has low polarity. Then, propanol has only one hydroxide and is the second-lowest polar molecular. Alanine has two points of polarity because oxygen and nitrogen have high electronegativities. Then, the ion sodium has a charge and has no stabilization such as the molecules, so it is the most difficult to diffuse.
Qc < Kc, the reaction proceeds from left to right to reach equilibrium

Given
K = 50.2 at 445°C
[H2] = [I2] = [HI] = 1.75 × 10⁻³ M At 445ºC
Reaction
H2(g) + I2(g) ⇔2HI(g)
Required
Qc
Solution
Qc for the reaction
Qc < Kc ⇒ reaction from left(reactants) to right (products) (the reaction will shift on the right) until it reaches equilibrium (Qc = Kc)

A ball slowing down as it rolls across a carpet is an example of friction.
Friction is a force that slows down moving objects.
