# What is the balanced equation for sugar+oxygen burning to carbon dioxide+water?

Dec 15, 2014

Sugars are a white crystalline group of soluble carbohydrates that are very sweet-tasting in nature. Sugar molecules include glucose, fructose, sucrose, lactose, maltose, and galactose, classified into two groups: monosaccharides and disaccharides.

Glucose - ${C}_{6} {H}_{12} {O}_{6}$ - is a monosaccharide and its combustion reaction is

${C}_{6} {H}_{12} {O}_{6} + 9 {O}_{2} \to 6 C {O}_{2} + 6 {H}_{2} O$

Sucrose (${C}_{12} {H}_{22} {O}_{11}$) - commonly called table sugar - is a disaccharide produced as glucose and fructose are joined together by a condensation reaction:

${C}_{6} {H}_{12} {O}_{6} + {C}_{6} {H}_{12} {O}_{6} \to {C}_{12} {H}_{22} {O}_{11} + {H}_{2} O$

Sucrose's combustion reaction is

${C}_{12} {H}_{22} {O}_{11} + 12 {O}_{2} \to 12 C {O}_{2} + 11 {H}_{2} O$
