Answer:

Synthesis Reaction

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

Explanation:

Step 1: Define

RxN:   2Na + I₂ → 2NaI

Step 2: Identify

2Na + I₂ → 2NaI

A + B → AB

  • A = Na
  • B = I₂
  • C = NaI
