These are: reaction, chemical formula, reactant, product, chemical equation.
If an object has changed its chemical composition it has been through a chemical change. If you can't reverse what has been done in any way (things like burning, mixing, rusting) it's a chemical change

The answer is physical because in physical they are 5 senses see, hear, touch,smell. The toasted marsh mallow you can taste it, smell it when you are far, touch it when you eat it, you can hear it when it comes out of the oven,and you can see it when it's on your plate.
No, freezing is not a chemical change. It is a physical one. It (freezing) is reversable, and the substance that is changing state to a solid or from a solid is not undergoing any chemical changes.

A chemical change involves a change in a substance's chemical properties (characteristics that describe how it interacts with other substances).A physical change involves a change in a substance's physical properties(characteristics that describe certain features one can see with their 5 senses).

During a chemical change the structure of molecules (as chemical composition) is changed. Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Change of viscosity - Change of the temperature - Visible formation of new compounds
