Answer:
All of the above.
Explanation:
Hello there!
In this case, according to the definition of the Lewis structures, which are represented by the valence electrons, we first identify that the N atom has five valence electrons and each fluorine has seven valence electrons.
In such a way, we cans say that N is the central atom due to its lower electronegativity, the molecule has 7+7+7+5=26 valence electrons and the three F-N bonds are covalent, therefore the answer is all of the above.

Double Replacement Reaction
Thermal energy is dependent on the mass. If objects have a different mass then they will have a different thermal energies.
We have to explain monochlorination.
Monochlorination is the process to introduce one chlorine atom in any organic compound.
Generally, monochlorination takes place by replacement of proton from organic compound. To do chlorination, Cl₂ or HCl is used as reagent.
Inntroduction of one Cl-atom in any organic molecule takes place through free radical mechanism.
The monochlorination of benzene is shown here:
