Step 1:
I'll solve this step by step with a clear explanation:

Step 2:
: Identify the Chemical Components

- Ammonia (NH₃) is a base - Vinegar (CH₃COOH) is a weak acid

Step 3:
: Understand the Reaction Mechanism

When a base (ammonia) and an acid (acetic acid from vinegar) are mixed, they react to form: - Water (H₂O) - A salt (ammonium acetate)

Step 4:
: Write the Chemical Reaction

\mathrm{NH}_{3} + \mathrm{CH}_{3}\mathrm{COOH} \rightarrow \mathrm{CH}_{3}\mathrm{COONH}_{4}

Step 5:
: Classify the Reaction Type

This is a neutralization reaction where: - The acid and base react - Hydrogen ions (H⁺) from the acid combine with hydroxide ions (OH⁻) from the base - Produces water and a salt - Neutralizes the acidic and basic properties

Final Answer

Neutralization reaction The key characteristic is the direct reaction between an acid and a base to form water and a salt, which defines a neutralization reaction.
