Answer: hello your question is poorly written below is the complete question
answer:
For N1 : sp³ orbital
For N2: p orbital
For N3 : p orbital
For N4 : sp² orbital
For N5 : sp² orbital
Explanation:
Determining the type of orbital in which the lone pair on each N atom will reside.
From the configuration attached below we can determine the type of orbital and they are ;
For N1 : sp³ orbital
For N2: p orbital
For N3 : p orbital
For N4 : sp² orbital
For N5 : sp² orbital
The amplitude of a wave is the distance between a point on one wave and the identical point on the next wave. The period and wavelength of a wave are inversely proportional.
Since we already have the balanced equation, we know that the ratio between 
is 
respectively.
So then we can set up a proportion to find the number of moles produced when 2.90 moles of Na react completely:
Then we cross multiply and solve for x:
Therefore, we know that when 2.90 moles of Na react completely, there are 1.45 moles of 
that are produced.
