What else can I help you with?
Would the sugar change take place without heating?
Heating sugar it is thermally degraded. But sugar can be modified also by other chemical reactions.
Does the sugar possess the same property before and after heating?
No. Sugar is a carbohydrate. After heating (or burning or charring) it is oxidized to carbon dioxide and water and the reaction is irreversible.
Why would glucose give positive result upon prolonged heating with seliwanoff's reagent?
Glucose gives a positive result with Seliwanoff's reagent upon prolonged heating because it is a reducing sugar that can reduce the reagent, leading to the formation of a cherry-red complex. This occurs due to the dehydration of glucose under acidic conditions, producing furfural, which then reacts with the reagent. The prolonged heating enhances this reaction, resulting in the characteristic color change indicative of a positive result.
How do you dissolve more sugar cube in a glass of saturated sugar solution?
By heating the saturated sugar solution, and then adding more sugar.
Does the sugar possess the same properties before and after heating your experiment result prove this?
Yes, sugar retains its chemical properties before and after heating, as it primarily consists of sucrose. However, when heated, sugar can undergo caramelization, resulting in a change in color, flavor, and texture, indicating a physical transformation. This experiment demonstrates that while the basic chemical composition remains unchanged, the physical properties can differ significantly due to heat exposure.
What does a result mean?
Result means out come of certain activity .Eg: What was the result of heating sugar in pan?
Would the sugar change take place without heating?

What compound was decomposed sugar or salt?
Sugar is easily decomposed by heating.
What changes occur when heating copper oxide and sugar?
When heating copper oxide with sugar, the copper oxide undergoes a reduction reaction where it loses oxygen atoms to form elemental copper. The sugar, on the other hand, undergoes combustion to produce carbon dioxide and water vapor. As a result, you will end up with copper metal, carbon dioxide, and water as the final products.
Does the sugar possess the properties before and after heating?
No. Sugar is a carbohydrate. After heating (or burning or charring) it is oxidized to carbon dioxide and water and the reaction is irreversible.
What will happen to sugar after heating?
it will become caramel
Can sugar be obtained from a sugar solution by heating the sugar solution and evaporating the water explain?
Yes - the sugar doesn't evaporate.

How do you compare heating table salt and heating sugar in a test tube?
Sugar kind of melts and turns brown but salt doesn't, it just heats up.
