\(\text{NH}_4\text{NO}_3\)
\(\text{N}_3\text{H}\)
Correct Answer: NH4NO3
Explanation:
In ammonium nitrate (NH4NO3), nitrogen exists in two different compounds within the same molecule:
So, nitrogen exhibits two different oxidation states (-3 and +5) in this single compound.
The other options contain nitrogen in only one oxidation state.

Match the following:
In the following, \( [x] \) denotes the greatest integer less than or equal to \( x \). 
Choose the correct answer from the options given below:
For x < 0:
f(x) = ex + ax
For x ≥ 0:
f(x) = b(x - 1)2
