I don't think he'll ever curve the final grade down. From what I've heard from my TA, he will only ever curve the final grade in people's favor.

Problem 9C.1 part d - naming the compound

For the compound [Co(NH3)5(SO4)]^+

What determines the order of the compound's name? I originally thought the answer was sulfatopentamminecobalt (III) ion, but I got the order incorrect. Why does the "pentammine" part go before sulfato in the name? Thanks.
