Answer

Explanation:

Step1: Understand heat - of - combustion definition

The heat of combustion is the enthalpy change for the combustion of one mole of a substance.

Step2: Analyze the given reaction

The reaction $\mathrm{C}{6}\mathrm{H}{12}\mathrm{O}{6}(s)+6\mathrm{O}{2}(g)\rightarrow6\mathrm{CO}{2}(g) + 6\mathrm{H}{2}\mathrm{O}(l)$ has an enthalpy change of $\Delta H=- 2840\mathrm{kJ}$, and the stoichiometric coefficient of glucose is 1 mole.

Answer:

A. $-2,840\mathrm{kJ/mol}$
