The Lewis structure the student drew is incorrect. The total number of electrons in bonds and lone pairs is equal to the total number of valence electrons available, then a valid Lewis structure is produced.
The correct structure is the following:
The structure that was drawn by the student was incorrect because the total number of electrons around Oxygen were incorrect, there were 6 instead of 8, which was against the octet rule. The correct structure should have 8 electrons around each atom.
Answer:
Explanation:
Hello,
For the given reaction:
In such a way, the law of mass action, in terms of the pressures of both A and B at equilibrium result:
Thus, by introducing the change , due to equilibrium, we obtain:
Hence, solving for by solver or quadratic equation, we get:
Finally, since the pressure of B at equilibrium equals the change, it results:
Best regards.
Answer:
Octet Rule is defined as the chemical rule in which atoms tend to form bonds in such a way that it completes its valence shell or tend to achieve the configuration of a noble gas.
Explanation:
The lithium is chemical element, which has atomic number 3. It has one valence electron in its outermost shell, therefore, it will require 7 more electrons to complete its octet.
The element nitrogen has the atomic number 7, such that it has 5 valence electrons in its outer most shell. Therefore, it will require 3 more electrons to complete its octet.
The noble gas Argon have complete octet, such that it does not require any electrons to complete its octet. the gas is inert and non-reactive.
The chemical element Boron has atomic number 5, such that it has three electrons in its outer most shell. Therefore, it will require 5 more electrons to complete its octet.
Hence, the correct option is Nitrogen.
