Answer:
ammonia: NH₃
Explanation:
The product is ammonium nitrate, with the chemical formula NH₄NO₃. This salt is composed of the cation NH₄⁺ and the anion NO₃⁻
Nitrate (NO₃⁻) is formed from the strong acid called nitric acid: HNO₃.
Ammonium ion (NH₄⁺) is formed from the weak base ammonia: NH₃.
Thus, the chemical reaction for the formation of the salt is the following:
HNO₃ + NH₃ ⇒ NH₄NO₃
