The correct answer is option 3. The degree of polarity of a chemical bond in a molecule of a compound can be predicted by determining the difference in the electronegativities of the atoms in a molecule of the compound. Electronegativities of the atom tell how the electrons are distributed in the molecule.
Actually when the oxpecker bird eats insects off the back of the rhinoceros. They are helping each other. The bird gets a nutritious snack while the rhinoceros gets those pesty and annoying bugs off of him. This is also called a S<span>ymbiotic relationship. When both organisms of different species work together to benefit the other.

Answer:
780 moles e⁻
Explanation:
N⁺⁵ in NO₃⁻ requires 2(5e⁻) => 1/2 mole N₂(g)
That is, NO₃⁻ + 2(5e⁻/mole N₂ formed) => 1/2N₂
NO₃⁻ + 10e⁻/mole N₂ formed => 1/2N₂
∴ 78 mole NO₃⁻ requires 780 moles e⁻ => 1/2(78) moles N₂ = 39 moles N₂
