Answer:
1 pair of nonbonded electrons
3 pairs of bonded electrons
Explanation:
N has 5 electrons in its valence shell while O has 6.
Lewis structure of NO²⁻ is in the image.
N is in the middle of the structure because is the less electronegative atom. 3 electrons of this atom are forming the bonds and 2 electrons are nonbonded.
As you can see, N has 3 pairs of electrons forming 3 bonds with Oxygens and there is 1 pair of nonbonded electrons.

Explanation:
a. 30 moles of H₂O
b. 2.33 moles of N₂
<h3>Further explanation</h3>
Given
a. 20 moles of NH₃
b. 3.5 moles of O₂
Required
a. moles of H₂O
b. moles of N₂
Solution
Reaction
4NH₃+3O₂⇒2N₂+6H₂O
a. From the equation, mol ratio NH₃ : H₂O = 4 : 6, so mol H₂O :
=6/4 x mol NH₃
= 6/4 x 20 moles
= 30 moles
b. From the equation, mol ratio N₂ : O₂ = 2 : 3, so mol N₂ :
=2/3 x mol O₂
= 2/3 x 3.5 moles
= 2.33 moles
Answer:
E) rate of appearance of C = 0.45 M/s
rate of the reaction = 0.15 M/s
Explanation:
2A + B → 3C
Writing rate law for the reaction:
<u>Rate of reaction</u> = - = - = → equation 1
Given that the rate of disappearance of A is 0.3 M/s
⇒ - = 0.3 M/s
⇒Rate of reaction = - = ×0.3 M/s
⇒<u>Rate of reaction = 0.15 M/s</u>
From equation 1, = - = ×0.3 M/s
⇒ = 0.45 M/s
or <u>the rate of appearance of C = 0.45 M/s</u>
