Question 15

A typical Lewis acid-base reaction:

$acid acid I.euvii$, H20\*CH3 I.euvii$,$

Question 23

$A solvation shell is the solvent interface of any chemical compound or biomolecule that constitutes the solute. When the solvent is water it is often referred to as a hydration shell or hydration sphere. A classic example is when water molecules arrange around a metal ion.

For the process of solid calcium chloride dissolving in water, the entropy change is negative since water molecules in the hydration shells of Ca2+ and Cl- ions are more ordered than they are in the pure water

Question 28

Question 30

$Molecular Polarity Boiling point\* 100 oc Water surrounding a cation Water surrounding an anion Boilin point = -161 oc Why do water and methane differ so much in their boiling points? Why do ionic compounds dissolve in water?$
