When the Rambam includes Physics and Metaphysics in the category of the Oral Law it seems to include chemistry. That is he says is he referring to these subjects as understood by the ancient Greeks and whether in Mishne Torah or in Aristotle we can see Chemistry being included.
Even though the actual Physics of Aristotle does not seem valid anymore, still the subject matter that the Rambam was referring to is clear.
On the other hand when the Rambam refers to Metaphysics, I think it is clear he means specifically the book Metaphysics of Aristotle. But then going by subject matter I think then one would have to include Kant and Hegel.
