Is burning a marshmallow chemical change?
Yes, burning a marshmallow is a chemical change.
When a marshmallow is burned, the chemical bonds between the molecules in the marshmallow are broken, and new chemical bonds are formed between the oxygen and carbon atoms in the marshmallow and the oxygen atoms in the air. This reaction releases energy in the form of heat and light, which causes the marshmallow to burn.
The chemical equation for the combustion of a marshmallow is:
C12H22O11 + 12O2 -> 12CO2 + 11H2O + energy
This equation shows that when one molecule of marshmallow (C12H22O11) reacts with 12 molecules of oxygen (O2), it produces 12 molecules of carbon dioxide (CO2), 11 molecules of water (H2O), and energy.
