Writing correct chemical equations requires that you know how to predict products of reactions. Even with limited experience, one can use a few guidelines to accomplish this. Seven frequently used elements naturally occur as diatomic molecules: H2, O2, N2, F2, Cl2, Br2, I2. This is how they should always be written in a chemical equation. States of matter should be indicated by (s), (l), or (g) and ions in aqueous solution as (aq).

Since N2 is added to CO2 for enhancing the power output, we consider the N2 molecule also. It is a homomnuclear diatomic molecule with no permanent dipole moment. It cannot decay radiatively from the v = 1 to the v = 0 level of electronic ground state.

The assertion D(r) =k2e2/r tells us that the attractional force near the ground state is inversely proportional to the square of the distance separating the two objects under consideration (no matter whether or not it gets weakened much more sharply beyond the zone near the ground state). We shall elaborate on this later. Next, we demonstrate that the constancy of the product dissociation energy D(r) × interatomic distance r is related to the scaling-symmetry properties of the Schrödinger Equation (section 4). In conjunction to this problem, what is known as Badger’s Rule will be evoked along with our approach to frame an equivalently interesting relationship: It is that, the vibrational frequency of a diatomic molecule occurs to be proportional to the power of 3/2 of its dissociation energy, the way diminished by the squareroot of its reduced mass (section 5). Finally, in section 6, we deliver our conclusions.
