Answer:
Chemistry concerns matter: how atoms are structured, how they bond, how substances interact with themselves and other substances.

How biology counts and performs calculations is math. I like to think of chemistry as the bridge between many things.
Chemistry cannot account for things like Young's double slit experiment, or waveforms, quantisation of photons, the Electomagnetic effect, quarks, strings etc. The list is endless.
Also, on a macro scale, chemistry cannot account for phase changes, such as water to steam.
