@orthocresol I am in favour of reopening that question, especially I think that the hw close reason is awfully misapplied. I do, however, fear that the community will try to close it again. If that were the case, then I wouldn't want to overturn them again. I'll leave the decision to you.

can't believe we're closing stuff like that ^^, but leaving stuff like that open: chemistry.stackexchange.com/q/86876/4945

@Martin-マーチン By the time I got back from work, 3 people voted to reopen, so I just reopened it.
