Answer 1

Answer:

Hi dude here is your answer..

Explanation:

1. a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.

2. Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by diffusion—or occasionally by more specialized processes of facilitated diffusion, passive transport or active transport.

3. Eggshells contain calcium carbonate, which is a base. The calcium carbonate in the eggshell reacts with the acetic acid in the vinegar to form a water-soluable compound, calcium acetate, and carbon dioxide (CO2) gas. This reaction dissolves the eggshell, but leaves the inner membrane intact, creating a naked egg..

4. When the egg is placed in pure water, water molecules will move into the egg through the process of osmosis causing the egg to grow lager. ... This is because, the cells of the membrane of the egg shell will be denatured by the heat and die off and will not allow water molecules to pass through it by osmosis.

5. When this is semipermeable egg is placed in a saline solution (hypertonic solution), exosmosis occurs and the egg shrinks due to loss of water to the surrounding environment. ... Here, the number of water molecules diffusing out due to exosmosis will be more than the molecules entering the cell.
