Some of these questions do have answers, but these answers have negative votes. Only questions with upvotes will be removed from the list. In addition, this list has new questions sprinkled throughout! That means other questions have become popular and need attention, please take a look at the list and answer what you see fit.

How you can help:

  1. Answer some of these questions!
  2. Edit questions to make them more polished.
  3. Start a bounty on some of the more interesting questions.
  4. Support askers and answerers with upvotes where deserved. If you take a look at the edits made to this question, you can find questions that have been answered by the lovely members of the community.

I modified a query to fit Chem.SE to give us unanswered questions (that are open) and have a high number of views. You can also run the query for one or two answers if you want.

I did find that there were some questions that were quite popular and disappointingly did not contain any answers.

If anyone would like to handle some of these questions, that would be amazing!

Please edit these questions as you see fit (and fix any weird tags.) There is a lot of re-titling to be done and much-needed language cleanup or clarity in the body of the questions.

Here is the query.

Below are the Top* 20 questions that need answers. Why twenty? I feel that more variety in the questions shown here increases the chance they'll get answers.

I will update the above list...

... periodically.

*Note: Some of the top questions are homework questions which only required a yes or no in comments. I thus excluded them from this list as they do not really require an answer.

Do please comment any objections to the posted questions and I'll find another to replace it.

    $\begingroup$ I put a bounty on the Raoult's law question and lo!, a very nice answer materialized. I suggest others consider doing the same for more of these questions. Thanks to Melanie for writing the query and this post. $\endgroup$ – Curt F. Dec 10 '16 at 20:29
