Question

Describe with an activity to prove that Burning of sugar is a chemical change

Answer 1

Explanation:

When heated over a candle, these elements react with the fire to turn into a liquid. The heat causes the sugar's atoms to combine with the oxygen in the air, forming new groups of atoms. Energy is released in this chemical reaction in the form of smoke and black soot.

Answer 2

Explanation:

• Chemical Change: When a substance reacts with another to form a new substance this process is called a chemical change.
• Sugar is made of carbon, hydrogen, and oxygen, when we burn sugar water and carbon dioxide are formed. This chemical change is called a combustion reaction.
• C₁₂H₂₂O₁₁ + 12O₂ → 12CO₂ + 11H₂O
• Hence burning of sugar is an example of chemical change.
