Which of the following is the correct balanced chemical equation for complete combustion of methane (CH₄)?
medium Q6 of 15
Step-by-Step Solution
Step 1: Recall complete combustion reaction
Complete combustion of methane produces carbon dioxide and water.Step 2: Balance the equation
Methane reacts with 2 molecules of oxygen to produce 1 molecule of CO₂ and 2 molecules of H₂O.Step 3: Eliminate incorrect equations
CO and C are products of incomplete combustion; H₂ is not produced in combustion.Final Answer:
CH₄ + 2O₂ → CO₂ + 2H₂O → Option BQuick Check:
Complete combustion methane = CO₂ + H₂O ✅
Quick Trick: Complete combustion methane → CO₂ + H₂O
Common Mistakes:
- Confusing CO or C as products of complete combustion.
