Question 1

1.

What are some key concepts/key words you can think of for Energetics part 1 (on ΔH, enthalpy)?
[don't list me all the enthalpies!]

Question 3

3.

By considering the interactions involved, explain why the standard enthalpy change of hydration of an ion is always exothermic.
(it may be helpful if you write an equation representing the hydration of an ion, e.g. Na+).

Question 4

4.

State your thought process when constructing an energy cycle based on a list of equations provided.
e.g.
1. Li+(g) + Cl-(g) --> LiCl(s)
2. LiCl(s) --> Li+(aq) + Cl-(aq)
3. Li+(g) + Cl-(g) --> Li+(aq) + Cl-(aq)
