Complete the Lewis structures for diazine (C5H4N2) showing the two most common resonance forms. Draw the Lewis structures with the formal charges minimized.

See explanation and image attached

Explanation:

Lewis structures dot structures that show the number of valence electron in a molecule. Sometimes, we show bonded electrons using a single line as in the image attached.

Two images are shown. They are the both resonance structures of diazene. The both structures only differ in the arrangement of electrons as we can see from the image.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
