Answer:
Synthesis
General Formulas and Concepts:
Chemistry - Reactions
- Synthesis Reactions: A + B → AB
- Decomposition Reactions: AB → A + B
- Single-Replacement Reactions: A + BC → AB + C
- Double-Replacement Reactions: AB + CD → AD + BC
Step-by-step explanation:
Step 1: Define RxN
RxN: NH₃ + H₂SO₄ → (NH₄)₂SO₄
Step 2: Identify
Combining 2 compounds to form 1.
NH₃ + H₂SO₄ → (NH₄)₂SO₄
A + B → AB
It is a Synthesis Reaction.
