Question

Balance the chemical equation : CH₄ + O₂ → CO₂ + H₂O

Answer 1

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
