How does the electronegativity difference between 2 atoms relate to the % Ionic Character of the bond? Choose the correct answer.

A.) The electronegativity difference is one part of the calculation of the % ionic character of a bond

B.) The electronegativity difference is exactly the same as the % ionic character

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. in the first step, nitrogen and hydrogen react to form ammonia: (g) (g) (g) in the second step, ammonia and oxygen react to form nitric acid and water: (g) (g) (g) (g) calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
