Sucrose, with the molecular formula C12H22O11, is a disaccharide composed of glucose and fructose. When subjected to heat, sucrose undergoes a process called caramelization, where the sugar molecules break down and rearrange, resulting in the formation of various compounds. However, sucrose does not decompose into hydrogen and oxygen.

The complete combustion of sucrose with oxygen produces carbon dioxide and water. The balanced chemical equation for this reaction is:

C12H22O11 + 12O2 → 12CO2 + 11H2O

In summary, sucrose does not decompose into hydrogen and oxygen. Instead, it undergoes caramelization upon heating and combusts with oxygen to form carbon dioxide and water.
