The balanced combustion reaction is C₅H₈ + 7O₂ → 5CO₂ + 4H₂O
Hence, Option (B) is correct answer.
What is Combustion reaction ?
Combustion reaction is a type of chemical reaction between the hydrocarbon and oxygen.
CₓHₙ + O₂ → H₂O + CO₂
What is Balanced Chemical Equation ?
The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.
The given reaction is C₅H₈ + O₂ → CO₂ + H₂O
Now we have to balanced this reaction
Reactant side Product side
C = 5 C = 1
H = 8 H = 2
O = 2 O = 3
In the reactant side there are 5 C atoms and in product side there are 1 C atom. Multiply by 5 in the product side.
C₅H₈ + O₂ → 5CO₂ + H₂O
Reactant side Product side
C = 5 C = 5
H = 8 H = 2
O = 2 O = 11
In the reactant side there are 8 H atoms and in product side there are 2 H atoms. Multiply by 4 in the product side.
C₅H₈ + O₂ → 5CO₂ + 4H₂O
Reactant side Product side
C = 5 C = 5
H = 8 H = 8
O = 2 O = 14
In the reactant side there are 2 O atoms and in product side there are 14 O atoms. Multiply by 7 in the product side.
C₅H₈ + 7O₂ → 5CO₂ + 4H₂O
Reactant side Product side
C = 5 C = 5
H = 8 H = 8
O = 14 O = 14
Now the equation is balanced all the atoms of reactant side and product side are same.
Thus from above conclusion we can say that The balanced combustion reaction is C₅H₈ + 7O₂ → 5CO₂ + 4H₂O
Hence, Option (B) is correct answer.
