It's a chemical change. The aluminum foil is rusting, which cannot be undone, meaning that this is a chemical change, not a physical. Physical changes can be reversed.
The reaction between aluminum and copper chloride is a chemical change. During the reaction, a chemical reaction occurs resulting in the formation of new substances with different properties than the original reactants. This is different from a physical change where substances maintain their original properties.
Bending aluminum is a physical change because the internal structure of the aluminum remains the same even though its shape has been altered. Chemical changes involve the formation of new substances with different chemical properties.
When aluminum chloride is added to a ferric oxide solution, a chemical reaction occurs where the aluminum displaces the iron in the ferric oxide, forming aluminum oxide and iron chloride. This results in a color change and the formation of a precipitate of aluminum hydroxide.
The dissolution of sodium chloride in water is considered a physical change because no new substances are formed - the sodium chloride remains as sodium and chloride ions in the water solution.
Melting ice with calcium chloride is a physical change because the ice undergoes a phase transition from a solid to a liquid without changing its chemical composition.
When copper chloride reacts with aluminum foil, a chemical change occurs. This reaction results in the formation of copper metal and aluminum chloride. The color change (from blue to brown/red) and the formation of a solid precipitate are indicators of a chemical reaction taking place.

Physical. It's still aluminum foil.
This is a chemical reaction; synthesis of aluminium chloride.

Sublimation is a physical change.
Dissolving sodium chloride in water is a physical change because the chemical composition of sodium chloride remains the same. The sodium and chloride ions are simply dispersed throughout the water, but they can still be recovered by evaporating the water.
Yes. Physical change is when you change the appearance but not the actual object. Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
Crushing an aluminum can is a physical change because the substance itself (aluminum) remains the same before and after crushing. The change in shape and size does not alter the chemical composition of the can.
Yes, wrapping aluminum around an apple is a physical change because it does not alter the chemical composition of either the aluminum or the apple. It is simply a change in the physical state or appearance of the objects involved.
