Answer:
Combustion reaction
General Formulas and Concepts:
<u>Chemistry</u>
- 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:
<u>Step 1: Define</u>
2C₂H₂ + 5O₂ → 2H₂O + 4CO₂
<u>Step 2: Identify</u>
Any organic molecule reacting with oxygen to produce water and carbon dioxide is a combustion reaction.
We also see from the RxN that is is a double replacement reaction.
