Answer:
balanced equation: CH₄ + 2O₂ → CO₂ + 2H₂O
Step-by-step explanation:
Given sample: CH₄ + O₂ → CO₂ + H₂O
- The carbon is same, so no need to change.
- Hydrogen 2 less on left side so putted "2" before H₂O = "2H₂O"
- so now, there is total 4 oxygen on left side to balance put 2 before right side oxygen like this "2O₂"
changes applied: CH₄ + 2O₂ → CO₂ + 2H₂O
