| September 15, 2021 | education
Heptane is an alkane (saturated hydrocarbon) with the formula C7H16. The combustion reaction is the interaction with oxygen.
The reaction equation for the combustion of heptane is as follows:
2C7H16 + 22O2 = 14CO2 + 16H2O
Left: 14 carbon, 32 hydrogen, 44 oxygen. Right: 14 carbon, 44 oxygen and 32 hydrogen. Therefore, the coefficients are placed correctly.
Answer: the sum of the coefficients in the reaction is 2 + 22 + 14 + 16 = 54.
