Which of the following is a redox reaction?
easy Q2 of 15
Step-by-Step Solution
Step 1: Identify redox reaction
Redox reactions involve simultaneous oxidation and reduction (electron transfer).Step 2: Analyze options
In H₂ + Cl₂ → 2HCl, hydrogen is oxidized and chlorine is reduced, so it is a redox reaction. Other options are neutralization, decomposition, or double displacement.Final Answer:
H₂ + Cl₂ → 2HCl → Option BQuick Check:
Redox reaction = electron transfer ✅
Quick Trick: Look for electron transfer to identify redox.
Common Mistakes:
- Mistaking neutralization or decomposition as redox.
