Diesel fuel for automobiles and trucks is a mixture of hydrocarbons that can be modeled by C₁₆H₃₄. Write the balanced reaction equation for the combustion of C₁₆H₃₄, and report the sum of the stoichiometric coefficients.

Question

Quizplus · Accepted Answer

The balanced chemical equation for the combustion of the given mixture can be written as: C₁₆H₃₄ + 160(O2 + 3.76N2) → 116CO2 + 67H2O + 134SO2 + 600.96N2 The stoichiometric coefficients add up to (116+67+134+600.96) = 917.96. However, since the question asks for the sum of ONLY the stoichiometric coefficients, the answer is rounded down to the nearest whole number, which is 917. Therefore, the answer is E) 117 (digit sum of 917).
