As everyone who's spent a couple of minutes moderating Chem.SE knows, the bread and butter of the close reasons is homework. I really want to stop this, for reasons discussed and agreed upon before.
My biggest nitpick is with how the "homework" close reason is used to close questions that do not show research effort. From the official SE stance, lacking research is a reason to downvote, not vote to close, even though science SE communities have become more lenient towards doing so because they introduced a close reason beforehand that was used for questions that lacked effort. One of the reasons the "Lacks minimal understanding" close reason got deprecated was its misuse as a "lacks research" close reason.
"research" isn't the same as "effort", but is one of it's more prominent categories. An OP may only show a bunch of badly formatted calculations, later edited, and it will count as "effort" and prevents question's closure.
For someone who knows the answer to a seemingly badly researched question, it isn't obvious at all how much research will lead to the answer, unless they're an active teacher/professor in that field, or know where the answer exists online. Furthermore, not everyone is familiar with the keywords and a professional chemists may get results in a few searches, while someone like me will get into search loops and ultimately end up confused with no useful info. All of this, while considering that almost anything can be answered with enough research, leads me to believe that for something that highly requires objectiveness like close-voting, "lacking research" is too fuzzy and subjective. IMO, what you should do when you see such question is downvote.
Also make sure to give this a read. Of course, as been said before, a community can override almost any decision about them, and tweak the less critical rules of SE if it deems it necessary for its health, and I'm just a user among many. I'm fine with all disagreements and opposing decisions. I wanted to request banishment of voting to close "lacking research" as homework on meta, but I wanted all of us to have it clear which mindset is more popular and how exactly should those questions be dealt with.
