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.

When aluminum foil is added to copper chloride solution, a chemical reaction occurs where the aluminum replaces the copper in the compound to form aluminum chloride and copper metal. This is a chemical change because the composition of the substances is altered. The physical change that occurs is the color change of the solution from blue to greenish-brown due to the formation of copper metal.

Is the reaction between aluminum and copper chloride a physical or chemical change?
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.
Aluminum bends easily is physical or chemical change?
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.
if sodium chloride dissolves in water what is it a chemical or physical change?
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.
What happens to ferric oxide solution when aluminum chloride is added?
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.
Is calcium chloride melting the ice a chemical or physical change?
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.
Copper chloride aluminum foil physical change?
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.
Is the reaction between aluminum and copper chloride a physical or chemical change?
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.
Is tearing aluminum foil a chemical change or physical change?
Physical. It's still aluminum foil.
Is hammering aluminum into sheets a physical change or chemical change?
Physical
What chemical change is mixing chloride and aluminum?
This is a chemical reaction; synthesis of aluminium chloride.
Is aluminum foil cut in half a physical or chemical change?
It is a physical change because it can be reversed. All you have to do is weld the foil back together!
Is tearing aluminum a physical or a chemical change?
Physical. It's still aluminum foil.
Aluminum bends easily is physical or chemical change?
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.
Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
Is crushing an aluminum can a physical irreversible change?
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.
Is dissolving sodium chloride a chemical or 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.
When crushing an aluminum can has it undergone a physical or chemical change?
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.
