What is the correct product of C7H16 11 O2?

The combustion of heptane (C7H16) in the presence of oxygen (O2) produces carbon dioxide (CO2) and water (H2O). The balanced chemical equation for this reaction is:

C7H16 + 11 O2 → 7 CO2 + 8 H2O.

Thus, the correct products of the reaction are carbon dioxide and water.
