Final answer:
The balanced equation for C₂H₄ + O₂ → CO₂ + H₂O is 2 C₂H₄ + 3 O₂ → 2 CO₂ + 2 H₂O
Step-by-step explanation:
The balanced equation for the reaction C₂H₄ + O₂ → CO₂ + H₂O is:
2 C₂H₄ + 3 O₂ → 2 CO₂ + 2 H₂O
To balance this equation, we determine the number of atoms of each element on both sides of the equation. We start by balancing the carbon and hydrogen atoms using coefficients, and then balance the oxygen atoms using fractional coefficients.
