Answer #1

16.

This kind of interaction is seen between an ion and a polar molecule. Ex: NaCl in H2O.

Here, the Na+ ion is surrounded by the water molecules in such a way that the oxygen atom(negative pole) is aligned towards the Na+ ion (Positive pole). And the Cl- ion is surrounded by the water molecules in such a way that the Hydrogen atoms(Positive) is aligned towards the Cl-(negative pole).

17.

Solvation is a process where the solute-solvent interactions are very strong enough to overcome the attractive forces present in the solute molecules. This is a physical process, but not chemical because, it involves separation of solute molecules physically.

18.

Solvent component is nothing but the one which is present in highest concentration and solute component is the others which are present in lower concentrations. Thus, the determining factor is concentration.

    Part 4 - Data Checks In the previous sections of this lab, you have already looked at one problem that may corrupt data on the Internet or other networks, packet loss. However, this is relatively rare and is easily handled as with TCP handshaking to establish a connection and request replacements for missing packets. Except in rare cases, an issue only arises if there is a bad connection with packet loss of 5% or more. Another issue that can arise...
