It is a chemical change, because a new substance is created, and you cannot reverse it back to the way it was.
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 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.
A chemical change of aluminum would be its reaction with oxygen to form aluminum oxide. This reaction involves the breaking and forming of chemical bonds, resulting in a new substance with different properties than the original aluminum.
Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
Physical. It's still aluminum foil.
This is a chemical change.

Dissolving in water is a physical 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.
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.
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.
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.
When you combine them it is a chemical reaction (change) yes, but them combined in a solution is a physical change.
A chemical change of aluminum would be its reaction with oxygen to form aluminum oxide. This reaction involves the breaking and forming of chemical bonds, resulting in a new substance with different properties than the original aluminum.
