Final answer:
The balanced equation for the combustion of glucose is C6H12O6 (s) + 6 O2(g) → 6 CO2(g) + 6 H2O(g), representing an exothermic reaction where glucose and oxygen yield carbon dioxide, water, and energy.
Step-by-step explanation:
The balanced chemical equation for the combustion of glucose is C₆H₁2O₆ (s) + 6 O₂(g) → 6 CO₂(g) + 6 H₂O(g). This reaction is important because it's similar to the process that occurs in our bodies when glucose is used for energy, though in our bodies the energy is harnessed in the form of ATP.
The equation shows the consumption of one molecule of glucose and six molecules of oxygen, yielding six molecules of carbon dioxide and six molecules of water, releasing energy in the form of heat. Balancing a chemical equation like this requires ensuring that the number of atoms for each element is the same on both sides of the equation.
The enthalpy of reaction (ΔH°) for the combustion of glucose indicates that the process is exothermic, meaning it releases energy - specifically, 2803 kJ per mole of glucose at constant pressure conditions.
