B
NO_2
C
NH_3
D
N_2H_4
Verified step by step guidance1
Recall that ammonia is a common nitrogen-hydrogen compound with one nitrogen atom bonded to three hydrogen atoms.
Analyze each given formula: NH_4 represents the ammonium ion, NO_2 is nitrogen dioxide (a nitrogen-oxygen compound), NH_3 is ammonia, and N_2H_4 is hydrazine.
Understand that the ammonium ion (NH_4^+) is different from ammonia (NH_3) because it carries a positive charge and has one more hydrogen atom.
Recognize that ammonia's correct chemical formula is NH_3, indicating one nitrogen atom bonded to three hydrogen atoms with no charge.
Therefore, the correct chemical formula for ammonia among the options is NH_3.
