Mauve, I see where your coming from slightly saying random facts, except that this is a subtopic from thermochemistry. The reason why the middle is called thermochemistry is that there is not really another title that I can place this information under.
Once I start talking about borne-haber cycles and Hess's law and cycles then that can go under a different node/heading/title. The first mindmap was an introduction before I start going into specifics.
Besides this is linking ideas together and in the past I have found that if I was to use the mindmap at the top of the page and expand from there then the overall size would be too big for me to print on anything smaller than A2.
I ask that you dont pass judgement on me yet and wait until I complete some more. The other fact is that with freemind (google it) I can export as notes as well and so this may be useful to more people than you may think, I may also add this to the wiki.
Any constructive critisism?
