No. Sugar is a carbohydrate. After heating (or burning or
charring) it is oxidized to carbon dioxide and water and the
reaction is irreversible.
It burns before melting.
You can do so by heating both, then mixing them together before waiting for it to harden.
Sugar is a physical property.
Heating sugar it is thermally degraded. But sugar can be modified also by other chemical reactions.
No; sugar is thermally decomposed by heating.
Burning sugar is not a property. Burning sugar is a chemical change. The ability to burn, flammability, is a chemical property.
Sugar is an organic compound, an important nutrient - not a property.
Sugar is easily decomposed by heating.
On heating sugar suffer a reaction of thermal dissociation; some new compounds are formed an also carbon. The dissociation depends on the temperature and the time of heating.
Yes - the sugar doesn't evaporate.
Solubility in different solvents is a physical property
No, because you can't boil sugar. It will decompose beforehand. However, you can distinguish sugar and salt by heating them. Sugar will melt and decompose before 300 Celsius. Salt will not melt until ~800 Celsius
it will become caramel
Sugar kind of melts and turns brown but salt doesn't, it just heats up.
By heating the saturated sugar solution, and then adding more sugar.
