Complete the three Lewis structures for N(NO2)2– by adding missing lone pair electrons and assigning formal charges. Do not add resonance arrow

Structure 1 formal charges:

N₁ = +1; O₁₁ = +1; O₁₂ = -1; N₂ = 0; N₃ = +1; O₃₁ = -1; O₃₂ = -1

Structure 2 formal charges:

N₁ = +1; O₁₁ = +1; O₁₂ = -1; N₂ = -1; N₃ = +1; O₃₁ = -1; O₃₂ = +1

Structure 3 formal charges:

N₁ = +1; O₁₁ = -1; O₁₂ = -1; N₂ = +1; N₃ = +1; 0₃₁ = -1; O₃₂ = -1

Explanation:

The formal charge of an atom in a molecule is the charge assigned to the atom if the electrons in all chemical bonds were redistributed evenly between the atoms.

Formal charge can be calculated as follows:

Formal charge =  number of valence shell electrons in the neutral atom − ( number of lone pair electrons + ½ bonding electrons)

Structure 1:

N₁ = 5 - 4 = +1

O₁₁ = 6 - 5 = +1

O₁₂ = 6 - 7 = -1

N₂ = 5 - 5= 0

N₃ = 5 - 4 = +1

O₃₁ = 6 - 7 = -1

O₃₂ = 6 - 7 = -1

Structure 2:

N₁ = 5 - 4 = +1

O₁₁ = 6 - 5 = +1

O₁₂ = 6 - 7 = -1

N₂ = 5 - 6= -1

N₃ = 5 - 4 = +1

O₃₁ = 6 - 7 = -1

O₃₂ = 6 - 5 = +1

Structure 3:

N₁ = 5 - 4 = +1

O₁₁ = 6 - 7 = -1

O₁₂ = 6 - 7 = -1

N₂ = 5 - 4 = +1

N₃ = 5 - 4 = +1

0₃₁ = 6 - 7 = -1

O₃₂ = 6 - 7 = -1

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
