It might be nitpicking but there are question titles that are imo wrongly asked. The question itself might be better, but those titles are simply wrong.
Here are some examples ...
"Theoretically"-questions:
- Theoretically, could we spend trillions and remove significant CO2 from atmosphere?
Theoretically nearly everything is possible and yes we could because money is something that has a given and no absolutely fixed value. If we were intelligent and social creatures, we would save our earth no matter how much it costs. - Is OClF5 theoretically possible?
Theoretically it is possible, it simply depends on the conditions. In the moment that I draw a molecule on paper, it was created theoretically. But is it possible to synthesize it on earth under conditions that we can control? I have no idea.
Those questions can mostly be answered by yes or no, while I tend to always say yes. Look at molecules ... if you draw them on a paper, they are made theoretically. But can they be synthesized? Maybe not to our current knowledge but that does not mean that is impossible. So "theoretically" isn't a good question-scheme.
- Theoretically, could we spend trillions and remove significant CO2 from atmosphere?
"Can"-questions
I'm not sure if this fits for every "can"-question but for many of them ... Nearly everything can happen but not everything is going to happen because it's probability is nearly zero."Is there a way for something ... ?"-questions
There is a way for everything and if there is no known way today, there might be a known way or anytime in the future. If the "real" question would be the same as the titled question there wouldn't be an answer except the simple yes.
Two last examples:
What Methods Would I Use To Powder Cotton?
There is absolutely no way, except mind reading, that anyone else than the OP himself knows which method he would use ...Why $\ce{[Cu(NH3)4]^2+}$ is a square planar species and not a tetrahedral species?
$\ce{[Cu(NH3)4]^2+}$ is absolutely not a square planar species. The copper is coordinated in a square planar way but that doesn't make the whole ion a square planar species ...
can
in them. There are 559. Try not to edit too many at one, we do not need to flood the front page. chemistry.stackexchange.com/search?q=title%3Acan $\endgroup$
