The answer to the question is shown as U238,92 to alpha + Th

But if you type in U to Th + alpha in the different order, this is not recognized as an answer. I have put this alternative answer in for now, but it ought to recognize a different order of the items should it not?

If the alternative form is a legitimate correct answer, then fine. You workaround should be OK for now. I think this should be handled by the chemistry checker, though.
