Decomposition Reactions. ... The products of a decomposition reaction are not necessarily going to be elements. This equation shows the decomposition of sugar (C 6 H 12 O 6) into carbon and water. C 6 H 12 O 6 C + H 2 O: Still, this compound is being taken apart and this is a decomposition reaction.

Heating sugar is a thermal decomposition reaction; a chemical equation is not suitable. The resulting substances are water, carbon dioxide and caramel (a complex material).

The sulfuric acid removes water from the sugar in a highly exothermic reaction, releasing heat, steam, and sulfur oxide fumes. Aside from the sulfurous odor, the reaction smells a lot like caramel. The white sugar turns into a black carbonized tube that pushes itself out of the beaker.

The chemical reaction we are most familiar with is that of melting: sugar decomposes at a temperature ranging between 184 and 186°C. This is a very recent discovery we owe to a team of researchers in Illinois.

I presume you are looking for the equation for the combustion of sugar? The general formula for sugar is given as $C_{11}H_{22}O_{11}$. Assuming complete combustion, you would end up with: [math]C_{12}H_{22}O_{11}+ 12O_2 \rightarrow ...

The overall reaction is written: C₁₂H₂₂O₁₁ → 11 H₂O↑ + 12 C. Turned to colorless water and black carbon, the sulfuric acid turns sugar black. ¹ The sulfuric acid needs to be concentrated to exert its dehydrating effect on sugar. ² This reaction should not be attempted, except by properly-trained laboratory personnel.

Sugar crystals do not melt, but instead decompose in a heat sensitive reaction termed ‘apparent melting’, according to new research. The research, published in the Journal of Agricultural and Food Chemistry and recently presented to the Institute of Food Technologists , goes against years ...

The dehydration reaction is a type of elimination reaction. C 12 H 22 O 11 + H 2 SO 4 (sulfuric acid) → 12 C + 11 H 2 O (water) + mixture water and acid Although the sugar is dehydrated, the water isn't 'lost' in the reaction. Some of it remains as a liquid in the acid.
