Incomplete response:
- I don't know.
- Sodium Carbonate (hepta-)hydrate? - but I think there should be a 2 after the Na
- this formula doesn't make any sense - the parentheses don't balance, and there are too many numbers
- Arsenic sulfide

NaCO3.7H2O is sodium carbonate heptahydrate
Fe2(Cr2O7)3 is iron (III) dichromate
As2S5 is arsenic (IV) sulfide
no clue about the first one

cmdr2006 has the others correct.
The first one is a citric acid. if you combine the "letters," C6H8O7 is the result, thus a citric acid.
