Answer:
CH₄ + 2O₂ → 2H₂O + CO₂
Explanation:
From the given problem;
White balls = hydrogen
Black balls = carbon
Gray balls = oxygen
Equation of the reaction:
1 carbon atom surrounded by 4 hydrogen + 2 oxygen molecules gives two hydrogen atoms bonded to one oxygen + 1 carbon atom bonded to two oxygen
CH₄ + 2O₂ → 2H₂O + CO₂
The reaction above is balanced.
