Alunite: Chemical Analysis

There are two parts and I need 2 pages 600 words in 2 days. I would send the complete instructions with a private message but here is what i want: a) A discussion (a bunch of paragraphs) that explain how the analysis was obtained (analytical methods and parameters), and your interpretation of the actual formula (were other elements present in small quantities that were not included in the calculation?, Why was the normalization target used used, as opposed to a different one). Two pages not counting table and/or figures. b) An explanation for the fact that the overall charge does not balance.
