Final answer:
The balanced combustion reaction for toluene is C7H8 + 9O2 → 7CO2 + 4H2O + heat.
Step-by-step explanation:
The balanced combustion reaction for toluene (C7H8) is:
c. C7H8 + 9O2 → 7CO2 + 4H2O + heat
In this reaction, 1 molecule of toluene reacts with 9 molecules of oxygen gas to produce 7 molecules of carbon dioxide, 4 molecules of water, and release heat as a byproduct. The balanced equation ensures that the number of atoms of each element is the same on both sides of the equation.
