The coefficient for Oxygen in the balanced reaction : 3

Further explanation

Given

Reaction

C₂H₄ + _ _ O₂ ⇒ _ _ CO₂ + _ _ H₂O​

Required

Oxygen coefficient

Solution

  • 1. Give a coefficient

C₂H₄ + aO₂ ⇒ bCO₂ + cH₂O​

C, left=2, right=b⇒b=2

H, left=4, right=2c⇒2c=4⇒c=2

O, left=2a, right=2b+c⇒2a=2b+c⇒2a=2.2+2⇒2a=6⇒a=3

The equation becomes :

C₂H₄ + 3O₂ ⇒ 2CO₂ + 2H₂O
