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.
Is heating liquid honey a change of state?
No. Simply heating honey, while making it less viscus, does not change its state. It remains a liquid. Unless heating is prolonged enough to cause evaporation, the honey will remain a liquid, so no change of state occurs by simply heating.
Does organic compound decompose at high temperature?
The decomposition temperature depends on the compound. But many organic compounds do decompose on heating.
How long should you leave on a heating pad?
It is generally recommended to leave a heating pad on for no longer than 20-30 minutes at a time. Prolonged use can increase the risk of skin irritation or burns. If you're unsure, consult a healthcare provider for personalized advice.
When tissue is heated above 60 degrees C what happen to the tissue?
When tissue is heated above 60 degrees Celsius, it undergoes thermal denaturation, leading to the irreversible unfolding of proteins and disruption of cellular structures. This process can cause cell death, loss of function, and damage to the extracellular matrix. Prolonged exposure to such high temperatures can result in burns and necrosis of the affected tissue. Overall, heating tissue to this extent can severely compromise its integrity and viability.
Explain why the iodine test gave such results upon prolonged heating?

How can compounds be seperated?
by heating
What would happen if it 20 degrees and the heating is not on and you turned the heat down to 19 degrees?
The heating will not come on
The process in which compounds are converted to oxides by heating them in the air is called?
roasting

What happens if honey is heated?
It will most likely burn if heated. But it depends because it also might freeze because heating can be changing it from -123 degrees Fahrenheit to -122 degrees Fahrenheit Therefore: Be more detailed in your question
How hot does the heating pad get when in use?
The heating pad can reach temperatures between 110 to 160 degrees Fahrenheit when in use.
What is the process in which compounds are converted to oxides by heating them in the air?
The process of converting compounds to oxides by heating them in the air is called oxidation. During this process, the compounds react with oxygen in the air to form oxides. This reaction is often characterized by the addition of oxygen atoms to the compound's molecules.

What are the harmful effects of heating fanta soda?
Heating Fanta soda can lead to the release of harmful chemicals such as carbon dioxide and potentially toxic compounds from the caramel coloring. It can also cause the soda to lose its carbonation and alter its taste. Heating sugary drinks like Fanta can also lead to the formation of harmful compounds such as acrylamide.
Can you melt ionic compounds in a Bunsen burner flame?
It is not recommended to melt ionic compounds using a Bunsen burner flame because the intense heat can lead to decomposition of the compound or produce toxic fumes. It is safer to use a method like heating in a crucible with a low flame or using a heating mantle for melting ionic compounds.
Why can some metals be extracted from compounds by heating carbon?
Heating carbon with metal compounds can help extract the metal because carbon can act as a reducing agent. During the heating process, carbon reacts with the metal compound, and the carbon removes oxygen from the metal compound, leaving behind the pure metal. This process is known as a reduction reaction.
