WARNING: Ammonium Back To Ammonia

 it is possible that ammonium breakdown frequency 354.750 Hz, reduces ammonium ($NH^+_4$) back to ammonia!  This is so wrong.  Together with ammonia breakdown frequency at 362.844 Hz, stable nitrite ($NO^-_2$) can be produced; which can then be reduced further using 299.792 Hz, to $O_2$ and $N_2$.

There is simply to much going on that can deviate from the ideal situation where diatomic gases, $O_2$ and $N_2$ are the only stable product.

Resonance frequencies are dangerous.
