The octet rule states that if the octet of an atom is complete, meaning it has 8 electrons in its valence shell, then it will not react. Xenon in xenon fluoride does not obey the octet rule because the valence shell of xenon in xenon fluoride contains 10 electrons, instead of 8. Xenon is an inert gas because its octet is already complete, which means this reaction does not take place under normal conditions.
Answer:
To gain stability
Explanation:
If the outermost shell is not completely filled with electrons, the element has one of the three options: gaining electrons, losing electrons or sharing electrons. By gaining or losing electrons, ionic compounds are produced. Sharing of electrons results in the formation of covalent compounds.
You have to find the reaction involving sodium iodide and ozone or O₃. If you search in the internet, the reaction would be
O₃<span>(g) + 2 NaI(aq) + H</span>₂O(l) → O₂<span>(g) + I</span>₂<span>(g) + 2 NaOH(aq)
</span>
Using the stoichiometric coefficients in the reaction, the solution would be
5.95×10⁻⁶ mol O₃ * (2 mol NaI/1 mol O₃) = 1.19×10⁻⁵ mol NaI
