Explanation:
Bond order is inversely proportional to the bond length.
In 
molecule. one nitrogen is double bonded to nitrogen and one oxygen is single bonded to nitrogen and hydrogen bond.
- Bond order between the (N=O) bond is 2 which means that bond length between the (N=O) bond is shorter than that of the N-O bond.
- Bond order between the (N-O) bond is 1 which means that bond length of the N-O bond is longer than that of the bond length of (N=O) bond.
Answer:
D) It has a different unit than atomic mass.
I googled it, here it is lol
It is 100 because a 5 and up means you round up. also the 9 makes it a 6 rounded up
If you could explain what “merkels” are, the question would be more clear.
