For all combustion reactions having the general formula, C_nH₂_n₊₂ + O₂$\rightarrow$CO₂+ H₂O, the coefficient for water will always be an odd number.

Quizplus · Accepted Answer

The number of hydrogen atoms on the reactant side is always even (2n+2), while the number of hydrogen atoms on the product side is always odd (2). Therefore, the coefficient for water must be an odd number in order to balance the equation.
