Answer 1

Answer:

Explanation:

Salt concentration inside the egg is higher than water but less than saturated NaCl solution. ... In salt solution osmosis will occur and flow of water is opposite direction , water will come out of the egg and egg will shrink in size.

Answer 2

Explanation:

Egg shells are basically calcium carbonate, if you put them in HCl it will make pores and will make it a kind of semipermeable membrane. since water moves from lower solute concentration to higher which we call it osmosis, so water moves out from egg to salt solution making the egg to shrink
