    Balmer series is for x -> 2. Try using the Brackett series which is for x -> 4.

    Also, there isn't a need for using a formula.
    Thank you!!

    Anyone that can help on Gold? I've tried various things like different chemotrophic bateria and different names of halobacterium and things to do with salinity etc. to no avail.

    I've even looked up studies on bacteria in conditions of high salinity.

    Is it something to do with evaporation lakes, or reservoirs or something? And also, are they sulfur-reducing bacteria or something?

    Any hints would be appreciated.

    What do you think might give a red colour? Then link that to bacteria someway.

    iron ions give it a red color and the pigment is called bacteriorhodopsin
    tried both they don't work

    for those stuck on the Rg question, it is indeed about 13c nmr and different environments for carbon, thats the biggest hint I can give you without telling you the answer straight away. I can confirm the answer is an integer between 3000 and 4000 as previously suggested.

    the gold question had me stumped for a while, the answer was quite specific that it was a name of an organism, but im no biologist so i cant tell you whether its a genus or a tree or whatever level it was classed. im guessing its the actual name of that organism, belonging to the Archaea kingdom. I typed the coordinates into google maps and went from there. it is hugely related to iron

    feels good to have completed it, good luck all

    No offense but I am in Year 11 and did the challenge on April 1st. You shouldn't just follow your education, I always learn extra things through research in books, on the Internet and from friends. Widen your horizons, maybe :cool:

    Thanks! As for the last question, am i supposed to multiply the carbon nmr results of theses molecules together or something?
