Respuesta :
The equation is said to balance if the number of the elements is equal on both sides. No, the reaction is not balanced as the number of elemental atoms on both sides of the equation is not equal. Thus, option A is correct.
What is a balanced equation?
A balanced equation has an equal number of atoms of the chemical elements in a reaction that are seen as their coefficients. The reaction between Barrelene and oxygen is not balanced.
The reaction is given as,
2C₈H₈ + 25O₂ ⇒ 8CO₂ + 18H₂O
Here, the number of carbon and oxygen is more on the reactant side, and the number of hydrogen is more on the product side.
The balanced reaction is given as,
C₈H₈ + 10O₂ ⇒ 8CO₂ + 4H₂O
Therefore, in option A. the reaction is not balanced.

Your question is incomplete, but most probably your full question was, Is this equation completely balanced? 2C₈H₈ + 25O₂ ⇒ 8CO₂ + 18H₂O
A. No, because the number of carbon, hydrogen & oxygen atoms on both sides of the equation are not equal.
B. No, because the number of oxygen atoms on both sides of the equation is not equal.
C. Yes, because all of the coefficients are in their lowest whole number ratio.
D. No, because the number of hydrogen atoms on both sides of the equation is not equal.
E. Yes, because the number of products is equal to the number of reactants.
