Is this prier to a lab you've done?
Answer:
c) non polar Covalent
Explanation:
this is a molecule formed by atoms of the same element . they both have similar electronegativities and thus cancel out . This makes it a perfect Covalent molecule . The fact that it's a symmetrical molecule makes it non polar. a symmetrical molecule is a molecule formed by the overlap of orbitals of two atoms of the same element ( that is to say , there's no dipole )
Start by writing the atoms balance:

Now, determine the change of oxidation states:

has oxidation state 0, so each N has to gain 3 electrons to become

.
That, means that you need 6 electrons to balance the charges, resulting in:
And the answer is 6 mole of electrons.
The answer to this is: solid
When there is more thermal energy, there are less intermolecular forces. I hope this answers your question ☺️☺️
