CongratulationsHow about some profitable ways of being green? Check this link for some great ideas:
5 is a mixture3 is most likely element, though every element has radioisotopes1, 2, 4 and 6 could be any of them, it is impossible to tell with this limited information (germanium is an elemental semiconductor, for example, whereas polyacetylene is a compound semiconductor).
I won't do your work for you but here is how you can element, found on the periodic table compound, can be written in a chemical formula and must be exact mixture, cannot write a chemical formula even if you know what's in it
