In your equation, the molecule Ca3(PO4) is not possible. I believe you just forgot the 2 after the PO4.
If that is the case, the coefficients would go as follows:
3, 2, none, 6
I think it would be adaptation and natural selection because both the terms are when an animal adapts to their environment. I hope this helps!

Explanation:
If the energy of the ground state E1 is known, then we need to measure the difference in energy between the energy levels E5 .and E1. We can obtain this by measuring the frequency or wavelength of a photon that is emitted when an electron moves from energy level E5 to E1.
From Bohr's model;
ΔE = E5 - E1
Hence;
E5 = ΔE + E1
