SIZIF [17.4K]

Answer:

See image attached and explanation

Explanation:

The stratospheric ozone layer is very important in absorbing high-energy ultraviolet radiation that is harmful to living systems on earth. The concentration of ozone in the stratosphere is determined by both thermal and photochemical pathways for its decomposition. Nitric oxide, NO, is a trace constituent in the stratosphere that reacts with ozone to form nitrogen dioxide, NO2, and the diatomic oxygen molecule. The nitrogen-oxygen bond in NO2 is relatively weak. When an NO2 molecule encounters an oxygen atom, it transfers an oxygen, forming O2 and NO. The chemical reactions involved are formations of NO2 following by reaction of NO2 with atomic oxygen for form NO and O2. The sum of both reactions show that the overall reaction is simply the reaction of ozone with atomic oxygen to form two molecules of molecular oxygen. Hence, NO only serves as a catalyst, it does not undergo a permanent change itself.

7. The nuclear model and the solar system model both show atoms with electrons circling around
Keith_Richards [23]

These models are similar because "both the nuclear model and the solar system model have concept of nucleus, electron, positively charged nucleus at center and electrons orbiting around the nucleus".

<u>Explanation:</u>

The points which showcase similarities among both the atomic structure and the composition of the solar system are like the large percentage of the mass centered in the core which is the nucleus or the sun. Attractive forces bring the structure together by application of electromagnetic force or gravitational force.

The existence of the external objects influences the stable state of other surrounding objects as suggested by Pauli theory of exclusion and gravitational disturbance. Overall on the basis of the view only, in both the model their is similarity like atomic model speaks about electrons orbiting the nucleus similar to planets orbiting the sun.
