Solution:-
- a=Carbon(c)
- b=Nitrogen ion(N+)
- c=Oxygen ion(O-)
Now
#1
Let's look at the EC of carbon(Z=6)

Now.
3 electrons are shared(1 with H_3C and 2 with N+)
Hence
Electron left unshared=4-3=1
#2
Lets look at EC of Nitrogen(N),Z=7

- Valency is 3
- It has already shared 3 electrons
But
Its Cation i.e N+
- Hence 1 electron it donated .Now it has valency 4
Hence
Electron left unshared=4-3=1
#3
Lets look at EC of Oxygen(Z=8)

But it is anion hence 1electron required more which us bonded
Hence
Number of electrons left unshared=0
Answer:
A, C, and D
Explanation:
The correct options that apply to the principal conservation of energy are A, C, and D.
A is correct because energy can neither be created nor destroyed. However, energy can be transfered from one location to another or be converted from one form to another. <em>Whether transferred to converted, the magnitude remains the same.</em>
C is correct because energy cannot be destroyed but can be transferred or converted. <em>Hence, if a body or a location loses temprature, then the loss is being gained by another body or location.</em>
D is also correct. A closed system is a system that does not exchange matter with its surroundings. <em>Hence, the total energy remains the same within the system. </em>
