Solution

Combustion of glucose:
A glucose molecule $(C_{6} H_{12} O_{6})$ reacts with $(O_{2})$ to form carbon dioxide $({CO}_{2})$ and water $(H_{2} O)$ .
$C_{6} H_{12} O_{6} (s) + 6 O_{2} (g) \to 6 {CO}_{2} (g) + 6 H_{2} O (l), ∆ H = - 71 kcal$
Combustion of glucose is an exothermic reaction as energy is released.
Therefore, the above equation represents the combustion of glucose.
