Is heating table sugar an example of a physical change?
No, it is chemical reaction because it is producing a new substance. In the presence of heat sugar breaks down into carbon and water: C(12)H(22)O(11) [Scientific Formula for Sugar] ----> 12C+11H(2)O [New substance formed]
Was there a new substance formed after heating the iron sulfur mixture?
Yes, a new substance, iron sulfide, was formed after heating the iron-sulfur mixture. Iron sulfide is a chemical compound that results from the combination of iron and sulfur atoms during the heating process.
Why does sugar turn to a brown liquid on heating?
When sugar is heated, it undergoes a chemical reaction called caramelization. This process causes the sugar molecules to break down and recombine, forming new compounds that give the sugar its brown color and characteristic flavor.
The expansion of matter upon heating is an example of what change?
The expansion of matter upon heating is an example of a physical change. This is because the substance undergoes a change in form or appearance without forming a new substance.
Is sugar water combination classified as a compound or a mixture?
A sugar water combination is classified as a mixture. This is because sugar and water retain their individual properties and do not chemically bond to form a new substance.
When sugar is dissolved in water is it a new substance?
No. The SUBSTANCE is still water, only now sugar is dissolved in it.
Is heating table sugar an example of a physical change?
No, it is chemical reaction because it is producing a new substance. In the presence of heat sugar breaks down into carbon and water: C(12)H(22)O(11) [Scientific Formula for Sugar] ----> 12C+11H(2)O [New substance formed]
Why is heating table sugar until its caramel a chemical change?
Heating table sugar until it caramelizes causes the sugar molecules to break down and rearrange into a new compound with different properties, such as color and flavor. This process involves chemical reactions that form new compounds, making it a chemical change.
Was there a new substance formed after heating the iron-sulfur mixture?
yes.
Is the dark substance on copper after heating a new substance?
The darks substance is copper oxide, formed when the copper reacts with atmospheric oxygen.
Was there a new substance formed after heating the iron sulfur mixture?
Yes, a new substance, iron sulfide, was formed after heating the iron-sulfur mixture. Iron sulfide is a chemical compound that results from the combination of iron and sulfur atoms during the heating process.
What new substance is made when amylase is added to starch?
Sugar
How powdering of sugar is a physical change?
no, powdering of sugar is a physical change as it does not forms into a new substance
Is powdering of sugar a chemical change?
no because chemical change means formation of a new substance but in powdering no new substance is formed

Where was white sugar originated from?
New Guinea
