What coefficient is placed in front of O₂ to complete the balancing of the following equation? C₅H₈ + ? O₂ → 5CO₂ + 4H₂O

Question

Quizplus · Accepted Answer

To balance the equation, count the number of each type of atom on both sides. The equation is C5H8 + ? O2 → 5CO2 + 4H2O. There are 5 carbon atoms and 8 hydrogen atoms on the left. On the right, 5CO2 provides 5 carbon atoms, and 4H2O provides 8 hydrogen atoms. For oxygen, there are 10 from CO2 and 4 from H2O, totaling 14 oxygen atoms needed. Since O2 provides 2 oxygen atoms per molecule, 7 O2 molecules are needed to supply 14 oxygen atoms.
