The chemical equation is balanced when : a = 1, b = 3, c = 2, d = 2
C₂H₄ + 3O₂ -----> 2CO₂ + 2H₂O
The given equation is :
aC₂H₄ + bO₂ -----> cCO₂ + dH₂O
reactants products
C 2 1
H 4 2
O 2 2 + 1 = 3
Now , multiply by 2 in CO₂ and H₂O and 3 in O₂, we get
a = 1
b=3
c= 2
d=2
C₂H₄ + 3O₂ -----> 2CO₂ + 2H₂O
reactants products
C 2 2
H 4 4
O 6 6
now all the atoms are now balanced.
Thus, The chemical formula is balanced equation when : a = 1, b = 3, c = 2, d = 2
C₂H₄ + 3O₂ -----> 2CO₂ + 2H₂O
