If there is a higher concentration of sodium on the left side of a beaker and the membrane is permeable to the sodium, which of the following will occur? \

sodium is going to migrate the left to the right side through the membrane

Explanation:

Differences in concentration of sodium produce a movement of sodium through the membrane until reach the equilibrium

A permeable membrane is a barrier that only allows certain particles to pass through them. Diffusion is a physical process whereby the particles move from a region of higher concentration to a region of lower concentration, and this movement occurs until the equilibrium is reached (same concentration in every region).

If the membrane is permeable to the sodium, it means that only sodium atoms will be able to migrate from one side to another. And according to difussion phenomenon, sodium atoms will migrate from the side with higher concentration to the side of lower concentration. So, a migration of sodium will occur from the left side of the beaker to the right side of the beaker until the concentration of sodium is the same in both sides.

2.carbon dioxide

3.helium

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
