A bond formed between a fluorine, F, atom and a fluorine, F, atom is likely to be____

nikklg [1K]

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 )

How many moles of electrons are required to reduce one mole of nitrogen gas (N2) to two moles of nitrogen ions (N3-)?

Makovka662 [10]

Start by writing the atoms balance:

$N_{2} -\ \textgreater \ 2N^{3-}$

Now, determine the change of oxidation states: $N_{2}$ has oxidation state 0, so each N has to gain 3 electrons to become $N^{3-}$ .

That, means that you need 6 electrons to balance the charges, resulting in:

$N_{2} + 6 e^{-} -\ \textgreater \ 2 N_{3-}$

And the answer is 6 mole of electrons.

How do thermal energy and intermolecular forces behave with each other?

julia-pushkina [17]

When there is more thermal energy, there are less intermolecular forces. I hope this answers your question ☺️☺️
