To be balanced the number of each kind of atoms in the left side has to be equal to the number of the same kind of atoms of the right side.

2C8H8 + 25O2 → 8CO2 + 18H2O

C balance:

left side: 2×8 = 16
right side 8×1 = 8

Then the equation is not balanced.

The other atoms aren't balanced either. You can check in the same way that I made with the C.

The equation 2C8H8 + 25O2 → 8CO2 +18H2O is not completely balanced.

Explanation

The equation above does not obey the law of mass conversation which state that the mass in isolated system is neither created nor destroyed in a chemical reaction. This mean that the mass of the product must be equal to the mass of reactant.

In the equation above the total mass of reactant is 2+25= 27

while mass of the product = 8+18= 26 thus the equation is not balanced
