Determine the number of bonding electrons and the number of nonbonding electrons in the structure of of2. enter the number of bonding electrons followed by the number of nonbonding electrons in the dot structure of this molecule separated by a comma (e. g., 1,2).

(4,20)

Explanation:

Oxygen di-fluoride or OF2 is a polar molecule, formed through the covalent bonding between one Oxygen and two Fluorine atoms.

Oxygen has atomic no. 8 and its electronic configuration is as below:

Oxygen has 4 electrons in the valence shell. It has the ability to share two electrons with other atoms through covalent bond and get stable.

The atomic number of Fluorine is 7, and its electronic configuration is as:

So, Fluorine atom  has the capacity to accept 1 electron to form 1 covalent bond or in the formation of the F- ion.  

The structure of OF2 is a bent structure with O atom sandwiched by two fluorine atoms like F-O-F. So there are two electrons on oxygen atom that are taking part in the formation of covalent bond with each Fluorine atom (Please dot structure in figure).

Now we can easily calculate no of bonding and non-bonding electrons.

Hope it helps! :)

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
